Paranoid and anxious!

This paranoia of losing the baby is about to drive me up the wall. I miscarried last year, and this pregnancy I have tried to be soooo careful about everything.. not going too far from the house, not too much activity, no sex... I have literally had sex twice in almost 4 weeks because I’m so afraid I’ll miscarry again. Please tell me I’m not the only one 🙁
