I need help I dont know what to do anymore!

I'm 6 weeks and 3 days pregnant and since 2 weeks ago my husband has been finding me more sexually attractive(Don't get me wrong it's nice) but I don't feel horny and I can't seen to get into the mood when he does not stimulation works and the sex is kinda painful even when I do get into it. he likes to do it a little hard and that's pro ably my fault because, I loved it hard like pounding into my cervix hard before I got pregnant. but now any penetration hurts and is uncomfortable. and I feel bad. and his dick is too big for me to a blow job and hand jobs just get boring to him. he also wants to do anal but I'm scared of losing my baby over anything. I had a miscarriage in July and this is my rainbow baby. any advise?
