Hello, My last period started April 30. My cycle is normally 28 days. I had unprotected intercourse on the 17,18,19 day of my cycle. My period is due on the May 28. I have been feeling bloated, fatigue (dozing off and exhausted all day) lightheaded and only a few times have I felt nauseous but never got sick. I know I could wait the 3 days to see if my cycle would start but I m curious if I could even conceive on those days of my cycle?
