4 DAYS LATE NOW

I took a pregnancy test at 10dpo & got my result which is the picture below & it looks like a vvvfl & then yesterday at 16dpo I tested again at night and I believe it was negative. But still no period ! I have had cramps & lower back pain like af is around the corner but nothing! I've also been having clear discharge along with dizzyness & ive been sleeping a lot lately. Like once I wake up I go back to sleep for another 1-2 hrs. What do you ladies think ?😭
