I have been feeling pukish for about a month or so.My periods have been delaying by 4 or 5 days for the past 3 or 4 months, but this time my date was due on 18th June but my period started on 11th June.I never ever had unprotected sex.The last time I had sex was in May(with condom on).I took a home preg-test before only 3 or 4 days before my periods started this time.I had exams last month and also have some assignments to complete, which are a cause of stress for me.Besides I have many other things about which I'm constantly stressed.Could stress be the reason for my pukishness, or is it something else?? I feeling pukish everyday after breakfast which doesn't stop until after lunch.Please help!
