My period in July started between the 8th to the 10th and ended completely on the 15th.. I should pay closer attention to my cycles but I don't.. Anyway, I got a BFP yesterday (August 5th) on a non-early 25 miu HPT with evening urine.. My question: Could the postive result be from having unprotected sex on morning of July 25th? Is it possible for a non-early HPT to pick up enough HCG for a positive result that quickly?
