hi, i keep getting headaches for the last 5/6 weeks, tired all the time and keep getting really random bruises on my legs along with everyone telling me i m mad and cooking myself as i m always feeling cold, the only thing that even helps a little with the headaches is drinking milk i end up with drinking a 4 pint carton of full fat a day, it helps with the sickness too but just curious, I ve done a pregnancy test and its come back negative i know there is something wrong just no idea what
