We DTD last night (Mon) without any protection...totally...unintentional.
I'd been having a hard time this month pinpointing ovulation. My CM was so scant. Here's the timeline:
Saturday: (BBT lowest dip)
Sunday: possible O @ night (BBT rising)
Monday: possible O @ morning (BBT rising)
Monday: unprotected sex around 0+12 or 0+20
Tuesday: BBT dip down...
Is it plausible that there would be implantation dip so quick?
