Learn everything about menstrual cycle with Flo: luteal and follicular phases, ovulation, period, fertility, symptoms, pains and many more!

There are two distinct cycle phases: the follicular phase and the luteal phase. 

The first day of menstruation marks the beginning of the follicular phase. During this phase, eggs are maturing in the ovaries. 

Ovulation occurs at the end of the follicular phase. Ovulation is a key process that splits the 2 phases. 

After ovulation, the luteal phase begins and the egg can be fertilized. If there is no conception, the uterine lining sheds and your period begins. 

Both the follicular and luteal phases are accompanied by different symptoms. Track your symptoms in Flo to get more accurate cycle prediction!
