9 days late on period & negative tests!

Emma • 💅🏼💋
I am 9 days late on my period and I have taken around 6 different tests... 2 at the doctors and the rest at home (both Clearblue & First Response) I am anxiously waiting and it really sucks... Has this happened to anyone else?? All of the tests have came back negative except for one that the negative line barely came up..
