Hello. I have been using birth control pills for several years. The dubious ratio could have occurred at the end of January / beginning of February - I do not know if the tablet was absorbed and I did not take an additional one (later the tablets were used rather correctly). We did not use a condom, but it was also intermittent intercourse (I thought then that the pill probably absorbed). A week after the first withdrawal bleeding, the tests were negative, also from blood. After the second bleeding, the urine test platelet also one line - sensitivity 10 (I attach a photo). I did the test at 3 p.m., in the morning I drank only coffee. Unfortunately, my last two bleeding sessions were scant, and I always had a strong one. It intensified only at night and during physical exercise, it was darker, but no clots. During the day, the tampon was half full after 5 hours (sometimes not even). After the last bleeding for 1.5 days I had brown spotting. Additionally, I have recurrent breast pain and darkened papillary areolas. Sometimes the back hurts. What can such symptoms result from? Can they be caused by pre-pregnancy stress (I have a new partner and a lot of stress at the university, in addition it would be an unplanned pregnancy) or by hormonal changes? I will add that the gynecologist examined my ovaries, everything was there correctly, took into account the possibility of the latter option, and added that with the current packaging it should calm down (unfortunately, the breast pain has returned, and the areolas are darkened all the time). Does it make sense to perform further tests or should I not worry about pregnancy?
