Does anyone have any tips or ideas of what I should do. I had a period jan 10--18. I'm 41 days in my Cycle and havnt had a period. I called my dr about two  weeks ago and he said wait till two weeks into march. I'm ttc so I want to know what's going on and I don't want to wait. Is there anything I can take to jump stArt things   I know I'm not pregnant because I took three pregnancy test about two weeks ago.
