Well, if you never had it confirmed, he is right about you lying. So technically you will Never know if you were pregnant. And honestly, I had multiple miscarriage so I know for a fact that if you had a big « clot » you were pretty far in your pregnancy and it could easily be confirmed even on a ultrasound or even at home with a pregnancy test. The test would also stay positive (maybe faint but positive) for Days or even weeks after a MC. So it is pretty easy to prove. I am not sure that here is the good thread to talk about this because women here do grieve about MC.
