So my husband and I have been TTC for almost a year now. I started spotting 4 days before my period and my period stated the next day (3 days before period was due). Cramping has been extra strong lately, I never remember it being this bad before. Last night the cramps were the worst and I went to take my tampon out. I noticed a very large clot on the side and top of it (more so than normal) I had also only put this tampon on 2 hrs before and it was already soaked. When I went to use the restroom I heard and felt this big plop. When I looked into the toilet there was a very large (half dollar size) clot in the toilet and my cramping had pretty well gone away. Could this have been a miscarriage?
