help..

Last week i’ve been nauseous and disgusted with foods.

I’ve also been having sharp pains, but now its just turned into lower abdominal pain at a constant rate. But they’re different from my regular cramps.

I’m supposed to start my period tomorrow, (nov. 1st) BUT, I started lightly bleeding, spotting? Yesterday, Oct. 30th. And have been today as well.

I’ve taken tests and they come out negative.

Should I wait a day or two after my missed period to test again? Could I be pregnant?
