I was bad about taking OPKs this month... Didn't take them for a few days and then yesterday took one and it had a big smiley face which is positive for ovulation. Nearly 2 hours later BD w my DH. Also used preseed. I swear it felt as though it worked..... And funny enough... I'm a huge stevie wonder fan and moments after we finished "signed, sealed, delivered" came on the radio. was my baby just signed sealed delivered ;) ??? I'm being very optimistic clearly.
