Full flow (day you need to use a tampon or pad) is considered CD1, CD2, CD3, CD4, CD5-take Clomid this night before bed. So as an example: Let's say you got your 1st day of AF (not spotting) tomorrow on Thursday that would be CD1, Fri - CD2, Sat - CD3, Sun - CD4 & Mon - CD5 - you would start Clomid this Mon. night. Yea, I am quite moody to begin with - kinda always have been. So I have to admit I have become more moody/irritable. I also have gained some weight which I'm not too happy about. I'm not sure though if it is from the Clomid or the Progesterone or both. Anyways I have always been quite thin - always on the low side of normal BMI for my height. Well, now my clothes aren't fitting all that great. I feel puffy. And with all the costs of my medical bills and everything else I can't exactly go out and buy a new wardrobe so I def need to start working out more so I can stay in my current clothes. How annoying.
