Okay I usually get my period every 26 days,but on the 26th day it never showed up. Onthe 27th day I took a pregnancy test that came out negative,and I also got my period three days later. Right before I was supossed to get my period one of my friends said that I act different and joked about me being pregnant. So I want your opininons on whether or not I am,and I also have a another pregnancy test I plan to take Sunday.
