I am 18 years old and I am having pcos and I last had my periods a year ago. I consulted the doctor and she gave me cream ncr 10 mg tablets for 5 days. After completing the course I got my periods in the morning and I also vomited after some time. It was bitter in taste and the colour was white. It was a year back I had my periods and before a month I had an sexual intercourse with my partner. He did not ejaculated inside but still now that I have vomited today when I got my periods I am quite tensed. Is there any chances of pregnancy? I am having my periods after a year and I vomited on the first day of my periods this morning. Is there any chance of pregnancy?
