My Fiancé and I have been ttc for about a year now with no luck we took a break still with no luck. I went to the doctor and got blood work done nothing was abnormal that I know of. I’m now on the 2nd month <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a>. Today is the first day off my period I purchased ovulation test as well as preseed. I am also taking prenatal vitamin ( 2 weeks). When should I start testing for ovulation ?? Glow estimates my peak day on Friday and Saturday of this coming week and I’m on a 28 day cycle.. any suggestions ?
