Rough sex while pregnant

Me and my boyfriend we go hard cord every time with have sex. I’m almost 11 weeks and I’m just scare I will hurt the baby somehow. What usually get me a little be scare is when my lower belly come against his waist while I’m moving back and forth on top of him. Every time we have sex I don’t feel any uncomfortableness or bleed at all (just pure pleasure)

Anybody in the same boat as me?

Makes me think I will hurt the baby somehow, I keep telling my partner to lets go slow no matter if I ask him to go rough, he keeps saying the baby is quite protected inside where he/she is.
