i am 5 DPO

Minahil

I am 5DPO and i feel super hungry all the time! Had constipation for two days but not any more. Cramps in lower abdomen, back and legs, frequent need to urinate and a lot gassy. Cramps are more like that of PMS but goes and comes back. Who else feels the same symptoms? Can i be pregnant having these symptoms? How early can i test this to get a right result?
