Hello I have an issue regarding my period. I had sex on the 27th november, 6th Jan and 12th jan. I had my period on the 25th december which was more brown than my usual period, but was still my period. My next period was due three weeks ago, have had no symptoms of pregnancy but each week ive taken a pregnancy test which have all been negative. I also used contraception and most times he pulled out with a condom still on. Im stressed and have been for a long time due to exams,a breakup.
