Ok so i had unprotected sex with my boyfriend about 3days after my last period here are some of the things ive notice since then ive been needing to urinate more frequently like every 20 minutes ive had a constant bloated feeling and i seem to have a couple of stretch marks on my stomach under my belly button, i am getting sharp pains in my back every so often and i am constantly tired for the last 2 weeks iv also taken 2 pregnancy text which came back negative

do i have to wait till my missed periond to find out if im pregnant

does anyone know what thins could be other than being pregnant because everything i read these are the symptoms

if anyone could give me any hep i would be so greatful
