It's been 35 days since I last had my period! I usually get my period every 20-24 days every month but it's been 35 days now and I'm just so confused i take a pregnancy test and it says I'm not pregnant so can a pregnancy test be wrong? I've been feeling very tierd laitly like I can never get enough sleep!! I used the bathroom a little while ago and I had some light spotting almost pink but it dosent look like my period it's so light

Any ideas what's wrong with me am I pregnant am I not ???? I'm dying to know ! 😩
