Ohh yeah if you have a history of clots, good ol fashioned pills probably aren't for you. But to be sure, that's something to discuss with your doctor.I should probably be on some because I have a heck of a time. I take pills like clockwork then. But I'm terrified because I have clotting problems and I always get bad side effects on meds. I had clots that made me lose my vision every so often. Tons of tests and BW done. Not good results.
