Well, you probably saw my post... I have had cramps since every day after I ovulated and just got my BFP today at 13dpo even though yesterday I swore I was getting AF (due to some light spotting and a bit of a temp dip). The cramps were exactly what you described. Felt just like AF, but not as strong (although the intensity of the cramps varied from light to mediumish.) Today got the BFP, the temp is back up, spotting gone, and I actually am tired and getting on and off hot flashes so to me it sounds very good!
