Can’t stop crying 😭

I don’t know if it’s my hormones or what.. but I can’t stop crying. 17 weeks pregnant and I have constant fear that something will be wrong. The 12 week scan soothed me for a week or so but before and since then it’s been constant worry. All I think about is that we will go to the heartbeat appointment and there will be no heartbeat, we will go to the 20 week ultrasound and something will have happened to our baby or there will be something hideously wrong, then we make it through all those things but then the birth goes wrong or I go into labour early.

I’m sick of upset and tears, I just want to enjoy my pregnancy. I’ve waiting two years for this 😭

Do I need to get help or is this normal?

Please be kind.
