Painful sex during pregnancy

I am almost 19 weeks pregnant with my second. During my first pregnancy I wanted sex all the time and it was 100 times almost more enjoyable. I came very quickly and it was just great. Fast forward to pregnancy number two. I had a miscarriage between having my daughter and this current pregnancy. That meant I was too scared to have sex for the first few weeks of this pregnancy for fear of bleeding and just freaking out over that. Now that I am 18 weeks and baby boy is growing perfectly we keep trying and I am so uncomfortable my husband can’t enjoy it himself. Anyone experience this? Solutions? Suggestions? It also doesn’t help that I have lost my sex drive this pregnancy. I obviously want to have sex regardless for my husband. Help!
