Hi, I started taking the pill about three months ago and have run into various problems since- any advice would be greatly appreciated!

I started off on alesse but was getting a lot of breakthrough bleeding, so I was switched to ortho 0.5/35 which worked well for a while, but the bleeding came back towards the end of the first pack. Usually i'd just push through it, but im leaving the country in two weeks and wont see my boyfriend for a year, so I just wanted a temporary fix, which is why my nurse switched me to the ortho. My roommate was having the same issues and she was switched from ortho to tri-cyclen which seemed to work. I changed two days ago and have had much heavier bleeding since- it's as if im on my period, with the back ache and stomach cramps and everything.

My question is, with so little time left, should I stick it out or go back to the ortho when at least I wasnt feeling sick and periody? Or is changing again just going to cause me more problems?
