🖤Linda🖤 • mom of 4💙💜❤️💜👩🏻‍🍼7/18/22

Has anyone had the same thing happen??? I'm on CD 29. I got 16 days of low then 3 days of high and today went back to low. I never got my peak days. This is my 4th cycle. The 1st cycle was 25 days with 3 days of high and peaked on CD 11&12. 2nd cycle was 22 days I never got high or peak days. 3rd cycle was 28 days with 8 days of high and I peaked on CD 17&18. I searched online and some women said they ovulated days before or after they peaked. I'm starting to think I just wasted money! I'm confused by all this can someone help I hope!
