13 weeks pregnant and no sex...

I’m 13 weeks & 5 days. Since i found out i was pregnant I have not had sex. I have no sex drive but since this is my first pregnancy, I’m actually scared to have sex. I was scared for a miscarriage the first trimester, so I was blaming the “NO SEX” on that. But now it’s like, I’m just not in the mood.

Any advice? Thoughts?
