Any insight? Super early ovulation?

Juanaa • TTC baby #2 💕💕

So last month I did a medicated cycle with femara and ovidrel. At my mid-cycle scan I had a size 29 and 27 1/2 follicle. My RE said size was fine but I never hear of other ladies reporting that size and it sounded too big to me. Anyways i had my <a href="https://glowing.com/glow-fertility-program">IUI</a> and I didn’t get pregnant.

Today I am cd 4. And I was having some pain on my left side, similar to ovulation pains so i decided to just take an opk for the heck of it. This was my result.

Any idea what’s going on? Can I possibly be ovulating this early in my cycle?
