Hey guys so last month I swore I was pregnant I even got a few faint positive tests but I ended up bleeding around June 23rd and figure it was my period, now this was an odd period it was way lighter than I’ve ever had and last only 4 days which typically I have extremely heavy periods for 9 days. So anyways fast forward we figured I wasn’t pregnant and started getting ready to try this month. I have had only negative tests but just started bleeding today (suppose to get my period in the next few days) the bleeding was medium heaviness but extremely painful like the worst cramps I’ve ever had. I just used the restroom in the last hour and noticed an odd blood clot, it was like like pink kind of lumpy and had what looked kind of like tissue in it. I’ve never had a clot like this, is it possible this was a miscarriage? I’m just trying confused.
