Sex while pregnant?

So I’m 18 weeks and my SO and I haven’t “done the deed” since he planted the seed 😂 tbh I just don’t feel cute and I’m constantly worried about hurting baby. I had a miscarriage my first pregnancy so I’m so over cautious and I know it.

Can anyone give me some reassurance? He has been so patient and hasn’t pressured me at all (he knows that I’m just scared). Help? I don’t want to make him wait 11 months lol
