Ethinyl estradiol / norethindrone
"I am 25 years old. Just started taking loestrin 24fe. Took it a week before my peroid. It's been two weeks since then. No period yet. Haven't done the deed yet so I dont know how effective it is. Started taking it due to being married soon (next week in fact). 
The problem Is I'm having shortness of breath and pain in my knee (thought it was pain due to walking home from work everyday, now not so sure. Could be a possible blood clot. My calf is hurting as well. I'm going to continue to take my pills but have compression socks on from now on to limit the clots if I have any.
I'm healthy (except I have synthyroid) only 25, so I shouldn't be having problems like this right? I'm keeping my legs over my heart as instructed to lessen the pain."
