Okay wel its been a month and 3 days since I've had my period, I feel sick, pee a lot, my lower stomach hurts, feels a little like cramping, I get dizzy and sometimes emotional. My boobs hurt a little, and even though I just ate a few hours later I will get so dizzy and start shaking and the only thing that stops it is when I eat, could I be pregnant? When should I take a test?
