When they had sex on a day that says 3%???? I another app I have it says I'm fertile between Dec 30-5 of January being the 4th that I ovulate, and here on Glow it say iam fertile between the 11-17 of January? My hubby and I have been TTC since april-may on and off(due to irregular periods). My first real period since June was in Nov 4-6, and then I got my period the 18-21, so when do you ladies think I'll ovulate, or does anyone know or has gone thru same thing?
