Yes, twice. DD was a whoopsie pregancy and was conceived well outside the ovulation period... about day 18 of the cycle. My last conception was at LEAST day 20 of my cycle... and I had a period as if normal but remained pregnant after the bleeding. I used to have quite long cycles of about 30 days... recently it has shortened back to the usual 28 days... but i can be irregular. I am starting to think I'm hyper fertile though... it's a bit of a worry now that i can't have children anymore due to health issues. Bring on menopause!

goodluck!
