Why am I spotting and urinating frequently suddenly?

Being slightly late­ for your period isn't abnormal, especially during stre­ssful times or bodily adjustments. The unprote­cted sexual encounte­r on February 7th, followed by taking eme­rgency contraception, could impact your cycle. That might e­xplain your delayed period. Re­member, stress, die­t modifications, and illness can also affect menstruation. If you're­ still worried, a home pregnancy te­st can offer clarity. 

There are many potential causes for this, but one is especially common: stress. When stressed out, it can throw your whole cycle off, leading to a late period. Missed periods can also be due to fluctuating hormones. If you’re concerned about being pregnant take an at-home test. 

Your fertile window is typically between days 11 and 21 of your menstrual cycle. Based on the dates given, February 6 and 19 were likely outside this period, so pregnancy is unlikely from those encounters. However, stay alert for signs like a late period or unusual tiredness.

See a gynecologist for an examination and diagnosis. Sores and lumps in the vaginal area could be caused by STIs, vaginal infections, cysts,etc. Only a doctor can diagnose the cause and provide appropriate treatment. It's essential not to delay medical attention for vaginal concerns to avoid further complications.

If you continue to experience symptoms such as missed periods or abdominal pain, even after a negative pregnancy test, it is important to consult a gynecologist for further evaluation.
