Feeling overly protective

So I’m 5 nearly 6 weeks pregnant with my first. And everything so far is ticking along well - however! I feel really weird about having sex with my husband. It feels like a no go zone because of our wee one down there. Although I know nothing bad is gonna happen from sex I just feel really odd about it!

That area in general I just feel really protective of.

Has anyone else felt that way? How long until you could feel normal about having sex?
