Clomid 50mg ??

Keisha • ttc #2 for 9 mos, have a 7 year old daughter. Ready for my next little pumpkin!
Hey guys. My doctor wants me to start on a cycle of clomid 50mg to assure ovulation. Has anyone taken clomid and got their bfp? Are there any side effects? Does it increase your chances of twins? Does it have to be done in conjunction with opk's? Should I take it even if I'm ovulating on my own? I'm so nervous and confused please help!
