For some strange reason my cycles range from 27-29 and last for 4 days. About 2 weeks ago i was cramping off and on again as though my period was on its way. Well on yesterday no period at all instead it's creamy, no odor, no burning discharge so i took a pregnancy test and it said negative. I have been taking vitamins would that be why it's kinda off balance? Me and hubby do want to conceive but when the time is right.
