My fertile window was Feb 9-14 and my peak was the 14th. I BD 11 12 13 14 15. My AF suppose to come on Feb 29. Yesterday my cm was very very very wet and pure white. I was in the shower all of a sudden I got nausea and threw up and after that I didn't have no appetite. I have been cramping slightly. No morning sickness or anything just cramps. Is this a good sign or is it to early ? I have an appointment to go to my gynecologist Tuesday because we have been trying for a year now. Do you think it's my time this month?
