rough sex.. while pregnant ( tmi)

Oh my gosh guys, the other day (I'm 13weeks) me and my husband were really in the sex mood.
He got creative and messed around that led into him fingering me then that felt so good I made him put more fingers in till it became fisting! That was pretty amazing! I want that again but the afterwards I was pretty sore and felt like he ripped me lol I never got that sore pre pregnancy!
We have been talking about having some good hardcore sex the past two days but we both get into bed and instantly fall asleep. 
Any ideas on new things to try or do?
Or creative ways to start off?
I'm just a little afraid of going that far again while pregnant lol or should I keep that up ha?
