I was on birth control (the pill) for about 6 months and my periods were regular. My last regular period was May 25, then two weeks later around June 10th I got really sick (not normal) and I ended up getting a period. That was the last time I have gotten a period. I was convinced I was pregnant so I went to make an appointment, 3 home urine tests and then a blood test all said negative and nothing in an ultrasound. I've been getting small cramps occasionally, painful sex, and still no sign of a period. I stopped taking birth control about a month ago and I have a doc appointment soon but I have have no idea what's going on, anyone ever have anything similar?
