Anything helpful I should know before I start? This will be my first month using and Dr. B told me I should start on the 3rd day after I peak on the CBEFM. I know I have to call him to confirm but how long do you use it for? Until your period shows? I'm trying 1 month naturally before I start IUI and am a bit nervous since he was stressing how important the timing is. Any crazy side effects I should look out for? Thanks!
