👸Jen♋️ • 38👸 with 👨‍👩‍👦‍👦, and 5 👼 as well as a 🐶& 🐈
So i got a positive opk on tuesday night 8pm and wed morning 12pm then negative wed night and neg friday. Then today I had another strong positive. I was just going thru the opk cause they were about to expire and was curious to see if i ever got any faint lines other then before i ovulate. I know i ovulated and i have never ovulated twice before. Wtf?!?
