A o device for the analysis of vaginal biological samples can include a sample collector, an extractor, and an assay cartridge. A method for the analysis of vaginal biological samples can include detecting the presence or absence of a pathology, a disease, an immune disorder, a reproductive disorder of a subject. The method may further comprise preserving, storing, or transporting the vaginal bio logical samples. A kit for the analysis of vaginal biological samples can include probe, reagents and instructions for detecting a nuc - leic acid in the vaginal biological samples. SAMPLE COLLECTION AND PRESERVATION DEVICES, SYSTEMS AND METHODS CROSS-REFERENCE [0001] This application claims priority to U.S. Provisional Patent Application No. 62/321,987 filed April 13, 2016, and U.S. Provisional Patent Application no. 62/460,329, filed February 17, 2017, each of which is entirely incorporated herein by reference. BACKGROUND [0002] Although accurate statistics on sexual assault are hard to come by, it is estimated that one out of every six American adult women has been the victim of an attempted or completed sexual assault in her lifetime. Considering the social stigma, shame, and fear associated with rape, it is not surprising that rape is t e most under reported crime. Accordingly, semen detection tests, confirmatory tests and forensic DNA testing are indispensable tools for solving a case of rape and assault in order to bring perpetrators tojustice. [0003] Along these lines, five of the top ten reportable diseases in the United States are sexually transmitted diseases ("STDs"). The Centers for Disease Control and Prevention ("CDC") estimates of February 2013 show that there are about 20 million new sexually transmitted infections ("STIs") in the United States each year, costing the American healthcare system nearly $16 billion in direct medical costs alone. The CDC's data suggests that there are more than 110 million total (both new and existing) STIs among women and men across the nation. Young people (ages 15-24) are particularly affected, accounting for half (50%) of all new STIs. Some of these STIs have the potential to cause serious health problems, especially if not diagnosed and treated early. [0004] STIs remain a major public health challenge in the United States, more so among women, who often disproportionately bear the long-term consequences of STIs. Women are more at risk for STIs due to the large surface area and the thin lining of the vagina. Women are more likely to be asymptomatic for common STIs and also have a greater biological susceptibility to infections. Women are also more likely to confuse an STI with a tame yeast infection or to have internal symptoms that may go unnoticed. STIs such as gonorrhea and chlamydia can lead to pelvic inflammatory disease ("PID") when left untreated. Chlamydia in particular can also cause asymptomatic infection of the fallopian tubes, and consequently, infertility. Furthermore, pregnant women have an increased risk of passing STIs to their babies, either during pregnancy or during vaginal birth. [0005] Besides STIs, there are myriad health conditions that are important, not only to women's health, but also to long-term fertility management. Reproductive cancers such as cervical, ovarian, uterine, and endometrial are of particular concern as they are often asymptomatic and present in late stages of disease. [0006] Many nutritional deficiencies such as folate, iron, and other vitamins essential for the healthy development of the fetus, and anemia caused by deficiencies in these minerals, can cause birth defects, allergy sensitizations, and preterm birth. [0007] Many hormones that work in concert to provide the optimal environment for pregnancy and fertility can often become dysregulated and may prevent a woman from getting or staying pregnant. Dysregulation can also cause diseases such as endometriosis and polycystic ovarian syndrome that may prevent a woman from becoming pregnant. [0008] Even during pregnancy there are many health factors that a woman can monitor to help reduce t e risk for preterm birth and infections such as yeast infections and Strep B. Fetal Fibronectin, which if found in vaginal secretions during 19-32 weeks of pregnancy can be indicative of a preterm birth. [0009] A cascade of changes occur during perimenopause as women transition into their non-reproductive years that can be measured and provide information to women on what is going on in their bodies at a chemical level that may help inform them of health and lifestyle choices as they age. [0010] Current blood-based diagnostic methods have reduced patient compliance because they require either a trip to an external facility, where a trained professional can perform venipuncture in a sterile environment, or a finger prick to collect a small aliquot of blood. Analysis of a blood sample is usually done in a laboratory by a different trained professional. Venipuncture in a doctor's office involves a non-trivial time commitment, travel and labor costs, and often psychological and physical pain that may prevent individuals from undergoing regular monitoring of blood-based health markers. Even finger pricks done at home can be psychologically daunting and difficult to enforce on a regular basis. In addition, finger pricks produce only a small amount of blood and subsequently limit the types of diagnostics that can be run at home. The friction that blood acquisition, alone, introduces into the health-care system down regulates the vigor with which consumers proactively monitor their health. [0011] Although other diagnostic techniques, such as the Papanicolaou ("Pap") smear, do not involve a blood sample, they still involve a trip to the doctor's office. Current vaginal swab technologies involve a specific swab that is inserted into the vaginal cavity. The protocol of collecting specimens from the vaginal cavity using a traditional vaginal swab is very precise, and an inaccurate procedure can lead to loss of sample and unreliable identification of desired biomarkers. Because of this, a trained medical professional typically administers vaginal swab collections. Moreover, the United States Preventive Task Force ("USPTF") currently recommends Pap smears only every three years. Even an annual checkup by an obstetrics and gynecology professional ("OB-GYN") may not guarantee a gonorrhea or chlamydia screening, and it may not be ideal to detect a pathogen that can lead to inflammation of the genital tract within weeks. This screening frequency impairs the identification and diagnosis of asymptomatic infections in particular. SUMMARY [0012] The present disclosure relates generally to a medical system for detecting and monitoring health conditions. In some aspects, the present disclosure relates to medical devices, methods, systems, and kits for collecting and analyzing biological samples from cervicovaginal samples, such as cervicovaginal fluid. In some aspects, the present disclosure relates to medical devices, methods, systems, and kits for monitoring a subject's health status. In some aspects, the present disclosure relates to medical devices, methods, systems, and kits for collecting and identifying a nucleic acid modification associated with a disease, infection, immune disorder, nutritional deficiency, pregnancy and/or reproduction disorder.
