subclinical hypothyroidism and TTC

Hi,

I have subclinical hypothyroidism tch = 2.9 and ttc for 10 months. My periods are almost regular (33-35 days cycle)

My dr recommended a very low dose of Synthroid (25mcg daily).

Anyone undergoing the same situation or had success stories?

Any one of you get an ultrasound done to check for cysts?

Thank you so much in advance for your responses ❤️
