no period 😟 - underactive thyroid?

Pri

hi girlies,

so I was diagnosed with an underactive thyroid about a month ago and have been put on a pill for controlling the same.

my period has been fairly regular since I started them.. about 31 days cycld.

however my last month period came like 6 days late and this month hasn't come as of yet ! ( I am 8 days late!)

I am not feeling any PMS either, however I have developed a few cystic acne on my cheeks.

does this happen to anyone ? is it normal for ppl with underactive thyroid to be late or like skip? should I be worried?

inputs would help
