I had protected sex and also took ipill in 2 hours , 1 week before my periods . First periods got delayed by 6-8 days. And when it came, it came for short period like for 3- 4 days with less bleeding. I also have tested after 7 days of sex for pregnancy test but the result was negative. And now after 2 weeks, i have started feeling pain in my stomach with some bad and different odor in my garment and different feeling in stomach. Is there still any chance of pregnancy?? Please reply asap.
