Lisandra • Mommy 🌺👦🏼 Wife 💍🌱🐢
So this is my first time using a fertility strips to help figure out my ovulation days clearblue advance fertility monitor . 2nd month using it and I passed my normal ovulating day . I have regular periods they're never late every month I get my period every 10th and get off the 16th . So my high Day last month was the 24th and the 25th & the 26th were peak days. This month I have not reached a high or peak all my test have been low on the monitor should I be worried ? Anyone that can give me any clue on what to expect or what's going on would be greatly appreciated.
