wondering if folks can give me some insight

i've had irregular periods for a number of years. often skip them all together. but i'm kinda tired of never knowing when i'll start one so i was considering birth control to help regulate.

thought it might help me figure out when i might be having pms vs. depression too.

i'm early 30's. currently take zoloft and wellbutrin for depression. i've never taken birth control before.

i really hate having a period and was thinking of asking the doc about one of those that allow you to just have four periods a year.

can anyone tell me if going on birth control could make me any more depressed than i am normally - considering it fiddles around with hormones?

also, i'm very over weight. doesn't birth control increase the risk of stroke...or am i imagining things?

i don't know... don't know if i should bother with it or not...

any opinions...input would be very much appreciated.
