Really bad anxiety in pregnancy

I had a chemical pregnancy last month and ever since then iv just had really bad anxiety about pregnancy. I'm so scared to have sex with my S/O incase the baby gets harmed, I'm scared to go out and do certain things, when I get out of bed I roll because I'm scared incase if I sit up or stretch it will hard the baby, Iv just got a constant fear that something bad will happen. Iv bought a fetal dopper and using it every night to listen to heartbeat so that I know everything is fine. I need constant reassurance everything is going to be okay. I can't help feeling this way it is horrible and taking over my life. Until I have my baby in my arms I will constantly have anxiety of negative things. I wish this would go away :(
