Dropping hormones

So I’m currently 5 weeks 2 days pregnant after suffering two early miscarriages. I’m freaking out because my progesterone originally was 23 and after about a week dropped to 9.5 and my estrogen dropped from 350 to 215. My hcg however is still doubling every 2 days and is currently 3600. My doctor started me on progesterone and assured me it’s normal for the hormones to fluctuate but I still feel like something may be wrong as I have no symptoms what so ever. Had an ultrasound today and doctor saw the gestational sack and fetal pole. Any similar stories that ended up with a healthy pregnancy? I won’t be able to handle another loss 😩
