Hey, I was just put on a Prevera to help start my periods again and I was wondering after taking the first dose how long did it take for you to start your period? Me and my husband has been trying to conceive without any medication but im trying this and hoping I don't need to be put on anything else.

So if it's ok when did you start? I've been having cramping and pressure but I also have a over active bladder and PCOS and Endometriosis so I am not sure if that's what it is.

HELP

Also when is the best time to take a ovulation test?
