I’m four days late on my period no sign of it still and was cramping in my back and lower stomach like it was going to start ? I got ache on my chest which I haven’t had since I was going through puberty ache on my forehead and sore breast which I usually get sore break 2 weeks before my period . And also I’ve been bloated for 4 days too and usually in the morning my stomach is flat I’m pretty small I’m 26 I weigh 127 and I’m 5 foot so very petit. Should I take a pregnancy test or keep waiting it out to see if my period comes ? Please HELP !
