Advice, please

Well, it's CD 2 again. We're going on vacation in July and I don't want to be in the first few weeks of pregnancy, so we're not doing any treatments until after our trip. Probably 3 cycles if we sit out this one that just started. I'm a bit undecided. I'm wondering if I should go on BCP for a few months (if I do sit out May) until we decide to start trying again... here's why. I bleed pretty much constantly. I have PCOS, and have had a uterine biopsy that was normal, except for showing no ovulation. But every time we have sex, I bleed. For days. Then mid-cycle I start another "period", or whatever for several days. I'm constantly cramping, bloated, etc.

It's never just light spotting, usually pretty heavy bleeding. I'm anemic to start with, and I'm just exhausted. I get terrible cramps and have a lot of clotting. I've got no energy and I'm gaining weight. I don't know what else to do but I need it to stop. Since clomid hasn't worked we're going to try something new, after our vacation. I have talked to my doctors and they think it is PCOS related, and that I can get on the pill but we obviously didn't go that route since our goal was to get pregnant. 

Also, any insight with going on the pill and PCOS? I have two friends that went on BCP after a diagnosis of PCOS and they both lost a lot of weight pretty easily because the hormones were more regular.
