Could I be pregnant?

Brianna

I’m not on birth control, and I don’t use condoms.. (pullout method) 😬. I got my period about a week ago but it was only for 2 days and then brown spotting here and the remaining two days ever since that started.. online it says that implementation bleeding isn’t like a normal period, but I was bleeding as if I was on my period the first day or two with cramping and extreme mood swings.. I’m going to take a test today but has anyone else had symptoms like this before?
