A lot of anxiety

Who else has gone through pregnancy loss? I lost my first baby at 6 weeks in high school, and my second baby with my husband at 29 weeks. We are currently 14 weeks 5 days with our third baby and I have so much anxiety. I've been able to feel her movements super early but all of a sudden I can't. Which I know is totally normal at this stage considering she is very small. I tried to find her heartbeat on the Doppler but couldn't, but I think it's because we are using it the wrong way. We saw the midwife on Wednesday though and she had a heartbeat of 160, and we went for an ultrasound appointment on Monday and she was very active I just couldn't feel her move. My anxiety is up the roof though and I can't stop thinking about the idea of going through another loss. I'm just so worried she isn't okay.. 😭😭😭
