Ive taken two hpt one on cycle day 25, and then on cycle day 26 af is supposed to show cd29 is it possible or normal to get two faint positives two days in a row? The second test wasnt much darker theyre about the same but there. Usually i get stark negatives. With it being so close to supposed af would they be darker or still faint and should it of darkened within a day of eachother even tho hcg doubles every 48-72hrs? Thanks.
