I can't relax. I always think something is wrong.

Following a chemical pregnancy and then a MMC at 9weeks I am now 18+5 with our baby boy. This entire pregnancy I have suffered with severe anxiety. It hasn't been straight forward. I bleed up until 13 weeks at one point filling the toilet with blood. All put down to a hematoma. I have been constantly obsessed with checking myself everytime I go to the toilet. When the bleeding stopped and clear watery discharge began I thought my waters had gone. Following speculum and regular scans it shows all normal. I have been treated for Strep b twice. I have also had regular cramps and aches which always make me think it's the beginning of labour. I am always checking what foods are safe and avoiding anything with known dangerous chemicals. I won't paint my nails or dye my hair. I've become neurotic. I have been assessed by mental health team and reffered to perinatal mental health but haven't heard from them yet. I'm struggling so much. People buy me baby gifts and It make me uneasy. Anyone else always worried about losing baby? Please no judgemental comments.
