Miscarry at 6 weeks

ally

Hi- I’m currently 6w+3days. I have been spotting after sex for 5 days now. But today was different, it was bright red and started to look like a normal period. I did blood work today and my numbers dropped by 250 points. I haven’t had any cramps or blood clotting. I’m aware this is the beginning of a miscarriage despite what NP says. Did you experience a miscarriage at 6 weeks? If so, how long did it last?
