hi, recently my body has been v strange, my period came a week early and was much lighter than usual, since then (about 3 weeks ago) I've been having heavy discharge most days and it feels like I'm coming on my period but i go and check and i haven't (it doesn't smell and isn't a strange colour) and I've had to poop much more often and sometimes its a bit like diarrhoea. i have had sit and pregnancy tests and both are negative. does anyone know what could be happening??
