SO and i had sex on the 17th & 18th of June, estimated O date of June 18th. usually when i ovulate i have slight cramping for a few hours, then it goes away this time however, I've had a dull, constant cramping feeling. i feel really good about it, but I'm trying not to get my hopes up too high! i just remember feeling crampy when i was first pregnant with my son. AF is due to arrive July 3rd, fingers crossed she doesn't show!
