Got ava for 30 days, so far it predicted 2 times ovulation, I am not that convinced. I'm under impression that it is simply "calculating the dates based on the past data I've input" and not using live bio statistics it is supposed to collect from me. I'm waiting for it to gather more data from me to "know me better" and see if it works any better.
Right after I got Ava, it predicted I was going to ovulate in a few days. On the predicted day, it says no enough sign show I've actually ovulated and suggested me TTC another day. -- However I got my period 19 days after that day, which is different to my expected 12-14 days gap between ovulation and period.
Now, almost a month later, 30 days after I've got Ava, it is predicting ovulation in 4 days. However I already got ovulation pain yesterday. (following 2-3 days of cervical mucus), either my pain & mucus was false alarm or Ava didn't get that message from my body. (I did forget to wear Ava for the first time, 2 days ago though, but only once.)
