Period after miscarriage

Kay 👱‍♀️👱👼🤰 🌈

I had a miscarriage last month and about 4 weeks later had a period, fairly light but lasted the usual 4 days. I didn't have my boob soreness either. I ovulated and had a faint positive so either residual or a chemical since I started my period yesterday and OMG! So painful 😭. I'm bleeding so heavy and the cramps and back pain is awful 😞. I read that the next period could be rough so my last period must have not be a "real" one. I'm just praying that this means I'm normalizing again so praying for our rainbow baby next month! Anyone else have this happen???
