Hello everyone, my name is Angie and I am new here. So I had my last period in Dec. but I was extremely tired and went to my doctor on Jan. 13th. I took a pee test to check to see if I was pregnant and it came back negative. I went off my bc because it was expensive and didn't start bleeding again till this past Saturday. On Sunday I was cramping really bad and then right before leaving church I felt something odd...like a huge blood clot falling onto my pad. I went to the bathroom and I started bleeding bad. We stopped at Walmart to grab a few things and I bled all over myself. Needless to say I went to the hospital and found out I was pregnant and my body was trying to have a miscarriage. The doctor took an ultrasound but didn't see anything. He said medically speaking he thought I was having a miscarriage, but I could be so early in my pregnancy that he couldn't find anything and the bleeding could have been something else. He said he could be wrong about the miscarriage and I should follow up with my obgyn. I spoke with my doctor and they are going to do some blood work this week and again next week to compare. I spoke to my husband and we are praying I didn't miscarry and I just had a clot burst or something. Has this happened to anyone else?
