HSG- Ovulation out of nowhere?!

I had my first HSG on Friday. I was expecting to ovulate next Thursday, but decided to start my testing (quantitative OPKs) and it was POSITIVE. I was shocked. I’ve never ovulated that early. We just happened to BD the day before yesterday, and we did as soon as I saw I was peaking, but I still feel confused and also a little disappointed because we didn’t get many “try’s” in this month. We were saving up for next week. 🤪😩😭 Has this happened to anyone?
