had a BFP on an OPK last night! I know it might not seem very exciting but its been 18 long weeks since I m/c and haven't had AF in all that time so to finally get a sign that my body's 'working' again, well I'm over the moon, to say the least!! So just wanted to say, I'm officially joining you ladies on the TTC forum!! Just one think I wanted to check, am I right in thinking that its the 36 hours after a + OPK that you're most fertile or has it already passed for this month? Thanks.
