rough sex?

I know that sex doesn't hurt the baby, (I'm 6 weeks by the way) but me and my husband have very rough sex... and he's very very large.... like we have sex almost every day and I still struggle to get it to fit everytime. I have had 2 miscarriages in the past and I want this baby so bad I'm just really scared. Even if the sex is very rough... my baby is safe right?
