i m 19 years old, 5 foot and 101 pounds. i m pretty healthy, no major concerns. There s a possibility i could be pregnant. i ve had common symptoms with PMS but this month it s way worse. i have severe cramping around right ovary , feel dizzy, tired, head ache, bloating , sick to my stomach, and have aversions to almost all the foods i eat lately. Could this be very early pregnancy or an ovarian cysts about to burst?
