Scared to have sex??

Edit: I'm sorry if this is stupid. I'm normally quite an anxious person and realize that pregnancy may be quite difficult as far as my anxiety goes.

Hey y'all. I'm currently 4w3d. I had a faint positive on an FR and then a positive digital on Monday. My doctor says I can wait to come in at 8 weeks for blood work and an ultrasound or I can do telemed tomorrow and get orders for lab work.

Anyways, with the positive digital I'm assuming it's real and just hoping for the best atm.

....so here's the thing. Since finding out this weekend we haven't had sex yet. But I realized tonight that I'm scared to. In my head I have it that it'll bring on my period or something. I know it's silly. I have no history of mc (this is my first pregnancy) but my mom had multiple and I'm afraid there could be issues for me too.

Has anyone else had this fear? Should I just let go and take the digital as "real" and just try to relax and go about life as normal? Or should I be extra careful until 8 weeks when I go in for all the scans and such?
