Period 1 month late ???

Arianna
It's been 30 days since my last period . I have no clue what's going on I took 3 test since the first 3 days of my missed period . The test were negative , I don't feel pregnant in the morning I feel weak and feel like vomiting but that could be anything . I truly don't want to get my hopes up . I've been crying a lot lately because of my boyfriends mom and family period treating me like trash for no reason. I'm uncomfortable eating sleeping being in his mom's house . I feel scared when I wake up someones gonna try and hit me . Maybe this stress is delaying my period 31 days .
