Short cycles when stopping fertility treatment

Hi ladies,

I was ttc for a while, including 2 rounds of timed intercourse using letrozole and gonal-f with trigger shot, and stopped in March.

Not surprisingly I had a weird cycle right after lasting only 16 days, but I’ve now had several short cycles since.

16, 15, 14, 16...

I’ve talked to the doc and am supposed to get bloodwork done in a few weeks to check my thyroid levels (I have controlled hypothyroidism) to see if that’s the cause, but levels were good while doing fertility stuff and I’m so tired of being on my period (and especially emotional when I am from the failed ttc).

Has anyone experienced this? Did you go back to normal? Was it your new norm?
