Sex way early on????

My fiance wanted to do the deed last night i told him ok but ur gonna go extra slowly lol he said why. I said well because u dont realize how much im freaking out being this early on n this pregnancy. With both of my other kids i was 2 months with this 1 not sure but guessing around 3 weeks he said well we dont have 2 do it if u dont want 2 i said its not that i dont want 2 im just 2 freaked out 2. He said well then we can just wait til ur further along and comfortable with doing it... is anybody else freaked out by being so early and wanna make sure u do everything possible not 2 hurt anything??
