So this might be a silly question but I just bought the clear blue digital ovulation test. I got a month supply (pack of 10). I don't wanna miss my peek day but I don't want to use them all up. My question is my got my AF on Saturday and it ending pretty much by Monday morning. It's seems that I have a short AF (I always have, 2-4 days is usually the length) and I also have a 24 day cycle. So when is the best to start using them? And should I BD every other day or everyday? I don't want to miss my peek day since I have a short AF and a 24 day cycle. I might ovulate earlier then day 14 like most ppl. How do you guys use them? Anyone like me with a short AF and a 24 day cycle? And today would be cycle day 3 or cycle day 4?? Sorry for all the silly questions, I just want this to finally be my month to be a mommy!! Thanks ladies!!
