I had taken the emergency pill within 12hrs of intercourse, I got withdrawal bleeding after 7 days, it lasted for almost 3 days and then it's been more than a month now, I haven't started periods yet, I'm around a week late. I have also been observing what they are called as early signs of pregnancy like I got light spotting around 10 days back. Then I feel more tired and sleepy than usual. I feel bloated often times and also feel like I have started to gain weight which never happened before with me, I have always been very thin. Are they all the possible signs of pregnancy? Can I still get pregnant even after withdrawal bleeding?
