Is it normal to be afraid after a miscarriage I feel like I'm over thinking it ?! 😢

Back in May I had a missed miscarriage and had an emergency d&c . In September I found out I was pregnant again. So far everything has been healthy and I had my 13 week ultrasound and everything was normal. It's like I'll feel fine after I see that everything is ok but that only lasts for a little while before I stress about it again. Whenever I get upset i use my home Doppler and listen to the babies heart beat and it's so relaxing to hear. I'll go through and read all these posts on here about other woman and there rainbow babies and it gives me hope, but then I see these people shooting them down saying that the baby can have an abnormal heart beat and u won't kno and something will be wrong so not be be relaxed when u hear it. My head is filled with so many things. I'm 15w and 3 days today but I'm still scared something will happen . It's like I can't enjoy this pregnancy because I'm to scared to.  I just need some advice at this point I really do. 💔😢
