*Please read! Sorry it’s a little long*

I am 8 weeks pregnant (due sep 20th) and I am absolutely terrified of having a miscarriage. I went to the doctor at 6w 4d and she confirmed my pregnancy. I don’t know why I am so scared or what to do to help. My first ultrasound is in a week and I feel panicky that there won’t be a heartbeat. I definitely haven’t had any symptoms of a miscarriage. I’m still nauseous all the time. My boobs are huge and painful. I’m exhausted all the time. I have definite food aversions, I’m extremely bloated, I haven’t had any bleeding or spotting. I had some cramping around 6 weeks but my doctor said that was completely normal. I have only told a few people that I’m pregnant and they all told me that they never even thought about or considered having a miscarriage when they got pregnant and that most likely everything is fine and I just need to relax. So why is this so hard for me?? I want so badly to just be happy and enjoy my pregnancy but I am just so scared and constantly have a nagging, worrying thought in the back of my mind that when I go into my next doctors appointment, they won’t find a heartbeat. I keep telling myself that once I hear the heartbeat I won’t be worried anymore but I know that I will just worry again until the next appointment. I am so tired of constantly worrying and don’t know how to stop 😭💔 Does anyone else feel like this?? Is there anyway to stop?? Please help! 😔
