What else would stop your period besides pregnancy and stress?

I can't get into the Dr's until the 29th. My period has been messed up for a few months, and now it's stopped. I've taken pregnancy tests and I'm not pregnant. I was also in the ER the other night, for dizziness and nausea. They said it was from stopping my medication and it would go away in a few days but I'm still sick. Do you have any ideas?

I wasn't on BC. I haven't been on BC for like 3 years.

There can be many reasons, ranging from chromosome problems to eggs not being produced. I have several friends who have massive problems of not having any for months then having 3 within a month and a half. I would go get some pills for the nausea etc, if your not pregnant it could be many other things. Mine used to be bad and they put me on the contraceptive pill to regulate them, it worked for me. Another thing is that I have another friend who had a contraceptive implant in her arm and it stopped her periods when it shouldn't have. I would not worry too much, and I hope you feel better soon! xxx

If you've stopped taking BC pills recently, it may take your body a few months to get back to its regular period.

Changes in diet or excessive exercise can also screw up your period.

If you have been doing lots of running

Weightloss or weightgain can have an impact on your periods
