period irregularities on armour

[Liz118]

I just started taking nature-throid (like armour without the fillers) about three weeks ago. My period just came two weeks early and has lasted a long time, almost 6 days now. Is this because of the thyroid meds? Should I be worried?
Thanks

Usually the difference in period appears if one is hypo or hyper. Or it could mean you are perimenopausal. (Don;t know how old you are  :)   ) If it continues to happen every month then I would get it checked out and have some hormonal tests done including an FSH and LH. Make sure your thyroid levels are are in check.

Hi Laura
I feel like I am slightly hypo now, because I switched from cytomel (15mcg) to the naturethroid. I don't feel as good on the naturethroid yet, maybe because of the time release not letting all of the t3 hit me at once? All of my hormone levels are low right now, but usually my period is regular. I take estriol but that has not effected my cycle before.
Maybe I am hypo?
Thanks

Make sure you test within 4 weeks after starting naturethroid to see if you are on target with dosage.
