Hello, I found this forum through Google and I hope to get some opinions...

My last period started around March 8th and we had sex on the 19th hoping to conceive. A short while ago I went to pee and wiped off blood. My period is usually regular, although I did go off the minipill in January so there may be some inconsistencies I suppose. What I'm really concerned with is a possible miscarriage? I have never had one to my knowledge, I have a 20 month old daughter...
