Sex in early pregnancy after previous miscarriages

This question might make me look dumb but I going to ask anyway. so try to be kind.

I’ve been pregnant 3 times before now and always ended in an early miscarriage/chemical pregnancy.

Idk if it had anything todo with it but every time the bleeding started, I was intimate with my husband the night before.

With those pregnancies my beta levels never went above the grey area of confirming. Usually was around 7-20 and never made it to get the second blood draw. so idk if sex really had anything to do with it or not.

Right now I’m 4w2d pregnant and my beta from yesterday was around 125 so the best beta I’ve ever gotten. I’m getting the pinching cramps that I never got with my other pregnancies so I’m assuming that’s little baby getting cozy in there.

My question is, do you think it would be safe for me to be intimate with my husband? I’m so worried about it. I honestly think the other times were just coincidental and bad timing but I still have a mind block about it. Send help lol
