My husband and I DTD on August 3, 10, 11, and 15. I have PCOS, so I'm not sure exactly when I ovulated, but it was sometime around that time. I've been super tired the past four or five days and I felt some cramping in my left side (could be due to sleeping funny?). I'm trying so hard not to symptom spot, but I keep doing it. Has anyone ever had fatigue as a SUPER early symptom before you ever missed a period? AF isn't due for a week or so, assuming my app is correct (PCOS makes my cycles anywhere from 4-6 weeks).
