Where the heck did my period go?

Hi. I've not had a period for 2 months. I'm not pregnant and recently had an exam and talked to a doctor, everything is cool down there.
I've not been under a ton of stress or had diet changes. I've always been a bit irregular, but this is strange.
I'm 30 and in good health, with the exception that I take Wellbutrin everyday and Ambien sometimes (was told it wouldn't effect girl problems).
Any similar experiences?
Thanks for help :)Where the heck did my period go?
The period gnomes took it.
Did you know that 4-5 times for your period is NORMAL
Maybe it went to the end of your sentence?
JK!
are you exercising a lot?
