A few months ago I had a weird feeling. It was a week before my due period but my bf and I hardly use protection so I tested. It was definitely positive. You could see the second line. Around when my period was due I started bleeding but a had BIG clots and a lot of them for 2 days my doc said false positives are very rare so it was most likely a chemical pregnancy. The egg fertilized but couldn't attach to my uterus. I was actually really upset. Being only 21 I was so stressed for that week after the positive test and I can't help but think it's my fault it failed and didn't stick. Has anyone else had this? Here's my positive test from 5 days before my period.
