New pregnancy after a loss.

In September I suffered a miscarriage of my first pregnancy after ttc for almost a year and a half. On April 1st after my first cycle of clomid I got the BFP (3 days before what would have been my due date). And though I am beyond excited, I'm still really scared. Am I completely paranoid because I don't want to have sex with my boyfriend? I mean...I want to, but I'm scared. I know I can't miscarry from sex...I am just so terrified I'll miscarry again. I guess I just want to hear a few rainbow baby stories to ease my nerves!
