Hair loss and then miscarriage?

I stopped taking birth control in March and not long after, my hair started falling A LOT more than usual. I attributed it to both the change in hormones and the stress of all that this year has brought (pandemic, civil unrest, husband lost his job and then was gone for 6 weeks certifying for a new one leaving me with our 1 year old trying to WFH).

We got pregnant in late June/early July, my hair still falling out- it’s so thin now. I miscarried at 9 weeks but missed it. Found out at 11 weeks there was no longer a heartbeat. I never imaged whatever was causing it could also cause a miscarriage but I kept seeing that hormones could have been the cause.

I had bloodwork twice since becoming pregnant and everything was normal there, but didn’t specifically test hormones. So no I can’t stop wondering if something is wrong that’s causing my hormones to be out of whack and in return is causing both my hair loss and my miscarriage.
