Are you sure AF full on? I know that many people note that they swore AF showed, with all the normalcy of AF, only to stop a day later and then find out they were in fact pregnant. I don't see a full on + sign in the pictures, so I would think they might be evap lines. And those evap lines are cruel. I had one month that I had 2 positives and I swore they were + and so did the OBGYN I showed them to, only to blood test and nothing.
