E3G levels in Mira Chart

Hi,

Has anyone had a cycle where your e3g got higher on the day of ovulation? It was my understanding that it should go down from the pre ovulation peak and in this case my e3g went up.

I woke up on the 28th with ovary pain, mostly on my right side, but It also felt like they were enlarged and uncomfortable. That got better as the day went on so I’m wondering if it was ovulation pain. Has anyone experienced that before?
Also, Mira has marked the day of my LH surge as ovulation day, but isn‘t the day of ovulation actually the day after the surge?

Lastly, has anyone had a chart that looked similar to mine that ended in pregnancy? I know it’s really too early to tell anything.

Thanks!
