Strawbell, I would go for it tonight or tomorrow morning for sure. Did you test super early this morning? What is your opk-taking schedule? IF you didn't take one since 9am yesterday, I would assume that you actually got a + yesterday and it is still + this morning so you will want to dtd tonight to catch that egg. Don't worry about timing, it doesn't sway. 24 hours is fine if your hubby has a normal sperm count (you can assume it is if your other kids didn't take much time to conceive!). Good luck!!!!
