Ok...this is a complicated situation! I have been on the pill for 7 years and honestly for the past 1.5 years I havent been a faithful pill taker. The month of June the first day of my period was June 14th. The last two weeks of June I was on antibiotics, which I was told would lower my bc effectiveness. The first week of July I was off my bc pill. July 9th I began taking it again, but I was skipping days and being forgetful due to a lot of stress in my life right now. On july 9th I had sex and my boyfriend ejaculated inside of me, and again on the 10th, and 11th, and the 16th. I have been experiencing severe fatigue, this past weekend I went to bed on Saturday night before 8pm and slept until almost 11am Sunday morning. My back has been aching incredibly bad and some days my breast feel sore. My period never came on the 14th, I thought maybe it was because my pill had been all messed up so it messed up my cycle. On July 25th I felt like I was getting my period, experiencing some cramping and then some slight bleeding, I decided to take a test but it came up not pregnant. I am not sure if slight bleeding can effect a pregnancy test or not. I put a tampon in but when I woke up on Monday the 26th, I wasnt bleeding anymore. Today I am feeling very very tired, can barley keep my eyes open at work. If I had become pregnant in early July, would it be possible to be having my period right now, or would I skip my period right away? I am just confused with this whole situation. The test says negative, but I am experiencing a bunch of symptoms. Please help me!
