Paranoia of miscarrying - I cant relax (10 weeks 🤰 pregnant)

Let me start by saying this is my first pregnancy and I am currently 10 weeks today.

This has been a long and bumpy journey. It took me approximately a year a half or so to get pregnant naturally (after trying two failed IUIs, in which my doctor said my husband and I had a slim chance of conceiving naturally without IVF)

With that being said, I’m so paranoid of having a miscarriage. I have never had one before and I haven’t had any bleeding or anything else out of the “norm”. I’ve had 2 ultrasounds, one at 6w2d with a heart beat of 119 and my last one measuring a bit ahead at 8w4d, and a heart beat of 173 at that appointment.

I have been paranoid this whole time and so worried about miscarrying since it took so long to get here. When I went my first midwife appointment on Tuesday she couldn’t find the heart beat on the Doppler and warned of me this since I’m quite early. But dang everything makes me so paranoid..that didn’t help 😞 I’ve only had minor symptoms of sore, heavy breast, increases appetite and maybe 3 little waves of nausea. I think that doesn’t help either that I don’t feel totally pregnant.

For some reason I feel like each time I see an ultrasound I’ll feel better or once I pass my 12 week mark I’ll feel better. But I don’t think I will. I’m on so paranoid of a silent miscarriage and have read people having them after 12 weeks.

Anyone else in this same situation, does it get better?? Any advice to calm my nerves?
