I have a question, I stopped my birth control (after 8 years) on May 21st, 2015. I got somewhat of a 2-day period at the end of June from the 18-20. Then I had sex (well my ex only was in for 30 seconds) so he didn't finish, on July 4th and worried about pre-ejaculation I took plan B on July 5th at 8:00 at night. I bled about 5 days later for 2 days and then on July 11th I had light brown spotting in my underwear again (IB?) all of July and beginning of August I was nauseous in waves but I got my "expected" period on August 8-10, again only 2 days but heavy enough for tampons. And then on the 13th I bled again for one day very heavy. I have taken about 3 pregnancy tests each month ALL negative. Now it's September and my period which was supposed to come on the 8th is 10 days late. Again 6 pregnancy tests ALL negative. I have no symptoms. I haven't had nausea not since July. I would be 9 or 10 weeks right? I would know by now right?
