i agree. the patch sucks! i think b/c it is a higher dosage, not sure, but i bloated too.
loestrin i believe is supposed to be low dose. i wouldn't just stop it w/o checking in with your doctor first. i would let them know about your concerns. also, they say to give it at least three months to see what effect it will have b/c your hormones have to adjust.
i'm currently on yasmine. i do like yasmine, i feel i have less overall side effects, but every month when i start them up again, in the beginning they kind of make me nauseas.
check out this link below for information on side effects, scroll to bottom to see chart. i hope this helps, but i would definitely speak to your doctor about any issues or concerns u may have.
