Hi, I have been having a regular period. Then I had sex on my fertile day in october, then in november I had a lot of symptoms like headaches, dizziness, nausea, hot flashes, fatigue. My period was 3 days later than it should have been and 1 day shorter than it usually is. I got my period this month and it was 5 days late and I have had a few symptoms like late month. I also have had some clear discharge with my period this month and last month. Can I be pregnant?
