opinions on different birth control?

Ok, I'm not on birth control. I use the pull out method (yes, I know it's not effective.) however, I'm considering being put on birth control because my periods are awful. I'm talking a tampon over-soaked within 2 hours with a thick pad on. I need to go to a gyno about it. Anyway, any suggestions on good birth control that is easy on the periods & won't make me gain a bunch of weight? My husband leaves for the military in a few months & I don't want to be on my period before he leaves. 🙄 I know everyone is different, but what do you use & what do you like about it? Did you end up getting pregnant at all even though it's 99.9% more effective then pullout ? How are your periods? Another thing, my periods are horribly irregular too. Does it make your period regulate? Any suggestions or advice would be very appreciated. I'm looking to set an appointment with planned parenthood & see what they can help me with.
