Hi, We Have Been Trying To Conceive For The Last

Hi,

We have been trying to conceive for the last 3 months with no luck. I am taking folic acid tablet since 2 months.Last month my periods was very heavy & painful. We went to gyno for consultantion & based on the blood test I was diagnosed with TSH 6.76. Sugar levels were normal. Doctor put me on 0.25 mg thyronorm.She advised we can continue to try to conceive.

I have been taking the thyroid medicine since then. This month, 15 days from my last period , I started having brownish infrequent bleeding for 4 days. I also have back ache, foot cramping & sole burning. No other usual PMS. My periods cycle is usually 28-30 days. I'm confused by the changed cycle, can this be due to the thyroid medicine? Should I take the brownish bleeding for periods?
