So no judgement please!!

So my boyfriend and I started having sex again a week and a half after my daughter was born😱I know I know you're supposed to wait but my will power is weak and anyways I had my period 3 days ago or at least what I thought was my period but it only last a few days and then stopped and now I'm cramping in my lower abdomen and my breast are heavy....
I just need advice please and please nothing rude!
Ps my daughter will be 6 weeks next Monday
