When I first missed my period I took a test 2 days after which were negative and the flo app told me to take another test after 5 days and on day five I had 2 positive tests and I have had more positive tests since so maybe you need to wait til day 5?
I was 5 days late on my period and I was not pregnant apparently, doctor told me to wait another 5 days and do it again and I was pregnant. Your HCG levels might be still low as it’s early days xx
@Charlotte I did take the first one with a normal boots test and it was a faint line and then four clear blues so I used two different brands
