Had my period, BUT...

Samantha
I had my period last week, it was like any other period other than it was 2 weeks earlier than normal. This week I am EXTREMELY fatigued like trying to not fall asleep at work. I'm extremely emotional and just want to cry, I've had an upset stomach (diarrhea, TMI I know I'm sorry) and today nausea and light headedness. I love food, but today at lunch as soon as they brought me my food I took one look at it and got nauseous and couldn't eat. Is it possible to have a period and still be pregnant? TIA
