I am 3 weeks late now! I usually have a 30 day cycle my last period started September 26th I took a ept when I was 1 week late another at 2 weeks and then on Monday I went for a blood test all are negative. I have been quite nauseous, moody, and the last few days extremely exhausted. I also had mild cramping last week and a small amount this week. I just want to know if I could be pregnant or if it may be something else like pcos , I did have unprotected sex the day before I ovulated! Anyone else ever have symptoms like this or have any advice?! Thanks
