So I had a positive pregnancy test and then a few days ago my test turned negative and I started to bleed a lot yesterday. I assumed I lost it but I took a test today and it’s positive...... My pee wasn’t even that concentrated. I had just peed. My negative tests were with FMU. The test at the doc yesterday was negative. He took blood and it won’t be back til Tuesday. What could it be???? Could it have been twins and I lost one? Was the hcg too high for the urine tests?? Not that I lost one it’s registering ?? Or maybe it’s an ectopic pregnancy???? This line popped up after a minute so it’s not an Evap???
