7-9 days flashing smiles on Clearblue??

Last month I had 9 days of flashing smiles on Clearblue opk before getting my solid on the 10th day (I almost gave up testing but didn’t). This cycle I’m not on my 7th day of flashing smiles. This is now my third cycle after miscarriage and thought things would be regulating by now. Anyone have similar experiences? This is now two cycles in a row with this, and I’m ovulating like five days later than normal (assuming if at all). I feel like I don’t know or trust my body anymore. I’m so frustrated!
