Feeling down

So after a yr of trying we started seeing an RE a little while ago. He ultimately diagnosed me with PCOS and mild insulin resistance. Started metformin and did one round of Clomid +and ovidril trigger shot (Oct 5th). I am currently 6weeks based on when I triggered. Initially my HCG was low at 13 and I was immediately told it was not viable. Continued to slowly rise to 16, 34 on draws 2 and 4 days later. Then saw some real action with levels of 199, and 815. I just got my latest result of 1500 , 3 days since the 815 so on the lesser side of doubling. On ultrasound ove seen the gestational sac twice and it grew about slightly. I go back next week for repeat blood and ultrasound. I'm hoping to see a flicker of a heart but my doctor keeps reminding me that it could still be non viable and an empty sac. I feel like I've been on such a rollercoaster already with this pregnancy. I'm exhausted and want to just hibernate til my next test. I'm trying to keep my mind off it but I can't. I'm also frustrated we never got our happy moment. From the second I found out my doctor has been telling me to be cautiously optimistic and I couldn't help but cry thanks to fear of miscarry and of course that's how hubby found out. I always expected TTC to be fun and exciting instead it's turning into an obsession and a depressing cycle of emotions. Just as I started to enjoy and embrace this pregnancy my results today make me worry yet again. I wanted to be happy and celebrate but instead we both are sitting here on pins and needles not sure what to think. Ttc with PCOS sucks. Rant over 😣
