Peri?

[MilkCereal]

How do you know when peri if on the pill? I'm 43, hypothyroid, tired, gaining weight, poorer eye sight. Do I go get blood tests?

There's little point in getting a blood test for peri as your hormones will fluctuate throughout, even from hour to hour. The only way to tell is from symptoms alone. It may be helpful to keep a diary of any symptoms but you may not be aware unless you stop taking the pill to see what your hormones are doing on their own.
