Do you have symptoms, other than the weight gain and problems with your menstrual flow?
I agree with gimel, if you could post recent labs, it be very helpful.
Sally - these situations are tough - but almost all thyroid patients get snagged up from time to time.
Its a hard knock learning process and now you know never to do that again.
Good Luck. You should adjust again just fine - and quick.... taking you were optimal shortly ago.
I'm curious about how you determine when you are okay, or not okay relative to thyroid issues. Are you basing it on how you feel, or test results? Could you please post some of your recent thyroid test results and reference ranges so that members give you their interpretation?
