Early ovulation???

Does anyone else experience early ovulation? The past two cycles I tracked my ovulation on CDs 7&8. Getting multiple peaks on opks and tracking bbt.

What is causing this? And is it going to make ttc more difficult?

I miscarried in November and thought that might have something to do with it, but looking back to when I bd in October it looks to be the same. We would have conceived CD 8-10. (Not exactly sure which but that seems early still)

Going to make an appointment with my OB of course but wanted your input! Thanks!
