to any female who's gone through this

[alilsick]

My question is to any female who's had to deal with this weird problem I keep having every month. I don't know if it's just me and me only, or it's a thyroid/female problem. The night before I start my period I cannot for the life of me get any sleep. I am on a prescribed sleep medication, ambien. I am diagnosed with hyperthyroidism. I've had sleep problems for the past maybe, three years and my Dr. had prescribed me ambien 10mg's and I take it when I have trouble sleeping. It works really well except when I am fixing to start my period, I do take it when I give up and cant get myself to sleep.The first day after I start, I sleep like nothing was ever wrong. Why? Am I the only one with this problem? It's not the cramp's, or hotflash's, that keep's me up, it's just frustrating to lay there really tired and desperate to try to sleep. is it thyroid related or something else I should check into?

Hate to be a party pooper, but the eostrogen and progesterone are all low at mensturation. Oestrogen rises dramatically at ovulation then drops again. In pregnancy it stays high, not so in a menstrual cycle.

Basal body temperature drops dramatically right before the start of the flow. This could be what is causing you the sleeplessness. You think about being in a cool room without enough blankets, you tend not to sleep well, same goes for the body having lost up to a whole point on the thermometer.

Progesterone levels drop slowly after ovulation and are at their lowest at menstruation. This being a type of steroid (yes it's true!) without it can also lead to sleepless nights.
Might be a good idea to have a warm milk drink before bed day before period starts.

it a surge in estrogen mixed with the progesterone that will release after you start to menstrate.

It will effect the thyroid hormone and cause a surge ( hyperT)  briefly until you start your cycle. Usually 24 to 48 hrs of the surge.
