Help!

Sarah

I’ve taken 2 tests today my second wee of the day as couldn’t quite hold the first for the school run but I’ve taken two in the same urine as I was watching the tests I saw 2 very pure lines but as I walked away and came back 3 mins later they were negative! I’m 2 days late today no signs of af at all but negative tests is it too early? Someone please help it’s real frustrating 😔
