Nervous

I’m 38 and had a missed miscarriage in December . Today I’m 8 weeks 2 days pregnant. What are my chances of having another one? I’m scared and panicing. First one was at 8 weeks four days and there was no heart beat we found out at 9 weeks so we never had any symptoms of anything being wrong which makes it even more scary. At 6 w four days we saw and heard heart beat and it was at 135 bpm. Next ultrasound is at 9 weeks on Friday . They checked my HCG levels early on and showed they were doubling. I am also taking progesterone every night. what are my chances of smtnng going wrong again. I can’t stop obsessing and worrying and we have had a lot of stress lately. My husband and I argue and I also have no symptoms which I’m paranoid about as I had no symptoms with last pregnancy either that ended in mmc. Please pray for me. I’m going to be 39 in June and can’t handle another loss. The other thing is my boobs looked bigger even a few days/ weeks ago and now they don’t... stomach looks a little smaller too. Now I’m worried maybe my levels dropped and that’s why I’m not feeling pregnant. Anyone who has had one miscarriage and then went on to have a healthy pregnancy can you please share your story? Before my 6 week ultrasound I was a nervous wreck then when everything r was fine I was relieved but now I am back to be same as I was before waiting for Friday to come.
