I have other questions on here but some background for what's going on. I am on birth control but the week before ovulation I had surgery/missed a pill/had to take antibiotics. I also had unprotected sex when I was ovulating. 1 week before my period was due I had some kind of brown spotting. A week later I started what I believed to be my period. The differences this time was 1. cramps, 2. lighter 3.only lasted 3 days when usually is 4-5 days. From my Google research haha I have found that being on the pill cancause your first missed cycle to actually still show bleeding. Cramp could be from my uterous stetching. I could have miscarried or had a chemical pregnancy, or it could be pregnant. I know my body and even if Im not pregnant now SOMETHING is up. I'm looking for experiences or answers of any kind as to what is going on. Also, I have a test left still and do't know if I should waste it or not. Thanks in advance!
