Obgyn... Clomid, No Cycle.....

Na
So today I called my Dr... She put me on clomid, I took it for my first time on Jan 27th... I am CD 36 today period is late, and I'm very concerned, especially since I'm getting negative pregnancy test.... So they told me by tomorrow I should be hearing from someone.... And am having light cramping, and hip pains on both sides, abdomen pain, ... I spotted on Feb 22nd when period was due and that was the last I saw anything else.... Sore breast as well.... I guess I'll keep everyone posted on what is said... But has anyone been concerned about this if it happens to you or am I just panicking????
