Got my first + OPK on my digital and cheapt test this AM. I have PCOS so this is truly a blessing. Cm is watery. We BD as soon as i got the +this am. It's now night time and i tested again, still +. Should we BD again tonight or wait until tmw night?! Either way we will BD again tmw night. Any advice on ways to catch the egg? So happy:)
