How can I tell if it’s a blood clot or a miscarriage? My “period” started today, I put in a tampon and like 2 hours later had cramps so bad I had to take it out and as soon as I took it out a huge clot or something fell out. I did have sex several times over the last month and one time he didn’t quite pull out in time so I know there was a possibility of pregnancy. This is also only my second period since having my daughter (10 months) so idk if maybe it’s just extra stuff that didn’t come out originally?
