16 days late

I’m 16 days late and I just got my period this morning. When I woke up it was heavy, now going to the bathroom several times, there’s barely any blood just a dot or two on the pads.

Now i was cooking eggs and well I needed to throw up so I went to the washroom, and I gagged but nothing came out..

I have cramps and I think I am getting a fever..some people say I am pregy and I don’t know what to do? Should I take a test? When?
