Ahhh...help!

Has anyone had AF type cramping and still been preggers? I am on day 25 and have had sore boobs for over a week.(this is unusual for me) Just in the last few hours I have had cramps/pains in my lower abdomen and a lower back ache - like I do before AF arrives. Only BFNs from HPT (i have done lots) AF due day 28 or 29 but I think I O'd early as my CM was early?

Any advice gratefully received....
