Letrozole buddies?! When did you ovulate??

Iesha • Married 💍 30. Angel baby 01.25.19 👼🏼 - 🌈💙July 24th 2020 ♥️ 🤰🏻w/ twins 💚💚

I’m currently on day 3 of letrozole (cd 3-7) 5mg for 5days and was told to DTD between day 10-20 (which would be jan 8th-18th). I know everyone’s different but I want to know. Hubby’s birthday is the 20th this month and I’m hoping to surprise him with a positive test for his birthday though it’s very unlikely because it’ll be too soon but I want to have some hope :)
