Baby #2 due in June.

Has anyone ever OV earlier than normal, and their doctor still went off their LMP?

I am only curious because I usually knew when I OV so I would avoid sex for that time being, and beings that I did , I ended up pregnant and had to have OV sooner than normal.

However my doctor can only go by my lpm since I don’t know the time I actually OV. My baby has been measuring 4-5 days ahead making it seem right to have OV about a week earlier than I should have.

Also if it helps, before I landed pregnant I just had a miscarriage before the sticky bean came along. So I’m guessing I OV earlier do to that?
