ISO Cycle Buddy

Last period 6/30--7/5. Predicted ovulation the fifteenth. And next period quoted as 7/29. Not sure how well glow follows and predicts your period. But I just started using the app last period. Figured its about time I figure out my cycle details. I've been told keeping track helps with chances of pregnancy. Just can't seem to keep track for the life of me. My approach?.. I get my period once a month, right around the same time, for a set amount of days lol. That's my philosophy and I think it's time to change that and educate myself. I'm a mom of a four year old girl and a two year old girl. TTC my third!
