Not sure

Billijo

So according to this app I am 8 days late. I had to run to the bathroom this morning because I felt like I had to vomit. I have been feeling back pain and cramping for the past few days. Yesterday I felt like I could not sit down and today more pain and nausea. I feel a some tenderness in my breast and like I keep leaking secretions no period. Do you think I should take a test?
