Im 29 years old and I really dont know what is going on with me, my last 2 periods only lasted 3 days which is unusual for me they usually last about 5 -6 days , my last preiod was on the 25th of febuary and lasted 3 days , the past 2 weeks I have had stomach cramps similar to period pains on and off ,some dizziness and slight nausea , Ive been irratible , weepy, very gassy burping alot, getting tired easily after a walk or housework, feeling bloated ,sensitive nipples, and my gums bleed when I brush my teeth now, I have done a preganacy test a few days ago but it came back negative , do you think im testing too early??? what is going on?
