And I don't know what to do!! it was never like this the first time I took them

They are making me nauseous at ALL times of day even when I take them with food! and once my tummy is empty again, I start to get nauseous some more

. Not to mention they make my boobs uber sore and give me REALLY bad cramps

I thought they were supposed to do the opposite? anyways I can't get off them because I REALLY need to be on some form of BC right now ( though I am ditching them in December) we can't use condoms because DF is allergic.(lubricant AND latex!!) I don't want to get pregnant, because we really can't afford it

the only other reason this would be happening would be pregnancy, but that is HIGHLY unlikely seeing as we only DTD 3 times last month and I haven't gained any weight.
what other forms of BC are there out there? any recommendations?
