Can anybody help I took a clear blue test 8 days before period too early to test I know but it came up with a faint positive. I then took another 2 pregnancy test the next day clear blue which both came up negative. Is there any change the positive was an evaporation line? I'm not due for another 6 days. I've been throwing up and feeling sick a lot headaches back pain the usual symptoms but I'm just abit confused to why the other didn't show positive if I am pregnant any advice?
