Early ovulation, I wasn’t ready!!

Monica • Pregnant with baby #3! Due December 20. 💗😍

So I wasn’t due to ovulate for another 2-3 days. But tonight I started to get super crampy. Like early labor feeling cramps! I decided to take an ovulation test and it came out superdooper positive! Hubby is at work until 3am. I’m afraid I’ll miss our chance for this month. If I’m getting the positive now how long of a window do I have??? I’d appreciate any baby dust you guys can send my way!! 🤞🏼😊
