Painful

Me and my man just did the “deed” and tried to do it on my stomach/doggie…. It started hurting really bad and has fully subsided. I’m only 6 weeks along as of tomorrow. Any advice on how to subside the pain or make that position more comfortable? Also any recommendations on how to make sex in general less painful AFTER words? Since conceiving it’s been kind of painful right after. I “potty” and everything. I don’t want to risk the baby for pleasure though.
