My last period (well I'm not sure if it was a period or not) I was bleeding but it didn't feel or seem like period blood and it lasted 6 days when usually my periods last 3 days the most. That was about 4 days ago. Period blood to me seems a little thick the blood that was coming out of my vagina was thin. I'm on birth control and am sexual active but I did skip a couple days on accidents and I'm not sure if I'm pregnant or not I have not had any symptoms my stomach has seem to have grown but I'm not sure it's cause i stopped eating healthy and I'm gaining weight or if I'm pregnant please help
