I'm 5 days late. Yesterday I did a First Response rapid result and got a very, very faint line and an IC which also had a very faint line. Done a FRER this morning and BFN, but the IC has come up with a very faint line again but stronger than yesterday's. What do you think? I would have thought the FRER should definitely be showing up strong by now, especially if a rapid response was showing faintly yesterday?
