Ok decided to use clear blue digital ovulation tests this month. I tested for the first time yesterday cd 12 around 4pm and got a empty circle. Ok. Then used fmu like recommended and this morning got a blinking smiley face. Don't wanna miss my window so held it for 4 hours and just tested again and got a solid smiley!! Could it be real? I know that sounds like a silly question but it just seems too good to be true?! We bd last night and I'll bd tonight to be sure but just looking for others experience using these!!! Thanks so much 😊
