Period Like Cramps day after fertility Peak??

Layla • Mammy to Sophia, who was 2 in June 💕 had a mmc end of Nov 18 😢, Pregnant with 🌈 👶🏼 💙 .. 👨‍👩‍👧 + 🌈👶🏼💙 EDD 12/11/19 🤞🏼💕

Ladies I got my Peak yesterday on my monitor and super positive ovulation stick, But this evening I’m getting pretty strong period like cramps ! 🤔🤔🤷🏼‍♀️🤷🏼‍♀️

I’m not sure what’s going on! I don’t normally get ovulation cramps, only an odd twinge occasionally!!

Anyone experience this???

Please help a confused person!! 🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️
