Hi - I am 5dp5dt after a FET and I tested late yesterday afternoon and got the top test. I thought when I woke up this morning I would get a much stronger line with FMU as the top one was after a day of drinking 2l of water but the bottom three this morning look same / even lighter! Has anyone had experience of this? When I have had FET before my tests darken every day (lots of pregnancies but 20 week miscarriage, ectopic and early miscarriages) so not sure if this is a chemical .. I guess time will tell.
