Pregnant or not

Nicole

Since Monday I have been experiencing sharp pains in my lower stomach and back. I’m tired all the time but my boobs feel fine. I am 4 days late but I took a 6 day early pregnancy test last Sunday it was negative. But this pain will not go away I haven’t taken anything just Incase. I was going to take a test tomorrow since it will be 5 days late on my period. But if it’s negative then I don’t know what it could be.
