This is my first cycle completely natural and off all types of birth control. I have been using OPKs for the last two weeks and yesterday I got my surge so assumed ovulation today. All day I have had wierd feelings down below, I wouldn't call them pains but just feel something and uncomfortable... Almost like AF may be coming but CD1 was only 16th Dec so seems very soon...? Took a test today and gt BFN (just incase the opk was an early pregnancy sign). Anyone else had this...? Not quite sure what's going on?
