I took a test using FRER 5 days before AF was due neg did another 4 days before and got a faint positive, waited til the day af was due and got a stronger positive.
Try again in a couple of days. Good luck x
Take one in 2weeks when hormone level will be pretty high. :)
Could be too early. I'm in the same boat. I'm due on the 20th too.
I would hang on in there, you could have a virus! 5 days before your due is quite a while and if you are PG the hormone may not be strong enough to detect a positive on a test! I say wait until your due and then take a first response early test. Good luck and don't worry too much!
