Months of bleeding, and then discharge?

Hello, I first started the depo shot in july of 2008. I had bled non stop so my docs put me on the pill Nov. of 2008 to regulate my period. I used the pill correctly all the way until Feb 2009. At the beginnig of Feb I stopped using the pill because it always made me nausiated. In May of 2009 they put me on the patch. If you've ever worn the patch, hopefully you can relate. Well, the patch was fine except it left patches (literally) all over your body. I still have the dark square imprints all over my hips, and . It also sometimes left Scabs on me. Any who, In November of 2009 i stopped using the patch. I couldnt stand to see my body like that. Here it is May 2010, and I have bled every day since November of 09. I finally stopped bleeding about 10 days ago. about 3 days ago i started noticing very light pinkish discharge. Some timesi it would be light brownish. Well i do have a fiance, and we have both been tested. Being that we were so happy i wasnt bleeding anymore, we've been having unprotected almost everyday. Could I be pregnant? Please dont leave any rude remarks--youre help is greatly appreciated!! thank you!!!
