i posted on here a while back about thyroid problems, my blood test results came back that i was borderline,(underactive i think) gp said it looks like its going that way, but not enough yet for medication, i have a re-test next week. i had an erpc new years eve, i still havent seen af. is this a symptom of a thyroid problem, i thought af was arriving last night, i had pink blood, then this morning only a tiny bit of brown blood, now nothing, we havent been using contraception, i did a hpt yesterday and it was bfn. i hope someone can advise me as im getting really worried now. thank you
