QUESTION

Renee • Just a girl in love.
I was prescribed Yasmin.... and right when I took the very first one I felt a cramp on my right leg and It feels heavy sometimes especially when I lay down and it's gone away now.
I know that Yasmin has bad reviews and I wanna switch. My question is should I stop? I'm gonna call my doctor tommorow but if I can't reach him I want to cease this and get a new one. 
Also, how long does it take to have unprotected sex if I'm starting a new one if my doctor prescribes one?
