Hey, so I thought I was out this month. My AF arrived 4 days late and only lasted 4 days with 1 heavy day which was unusual because I'm a 7 day girl with 4 of those days being heavy. However, I'm now on cycle day 9 of my new cycle and have been feeling so ill, I keep getting waves of nausea and headaches. I took a hpt and got a faint line within the time span. I also got a strong positive on an opk but didn't think this would happen until day 14/15? What do you think?
