Ladies I have a question ....

The past two weeks I've been feeling nausea , swollen feet , bloated stomach , weird cravings , and I hate the smell of some things like candles ( I love candles too ) and I feel most nauseous at night time before I go to bed and Saturday and Sunday I had brownish/ pinkish stuff like it was my period but I never had my period and I kept on spotting both Saturday and Sunday and it stopped Sunday night .. I don't know if I'm pregnant or not .
