Why did I ovulate early?

Melissa

I’m hoping someone has any suggestions because I can’t find anything on the internet!! I’m on my third cycle of Clomid. The first was 5-9 and the second was 3-7and I O’d both times on day 18. This time I did 5-9 and I O’d on day 15??? I thought I had just entered my fertile week so I started doing OPK and it was positive!!

I’m only day one after but my temp went up so I’m pretty sure it happened.

Just frustrated as we only BD on O day then..... I thought I had 3 more days!! 😭
