I had an intercourse with my gf on 10 may she is 19 years. Then she consumed unwanted 72 in doubt on 11 may. Then her periods came after 1 week i.e on 18 may and lasts for 4 days only and ended on 21 may in a very few amount than usual .normally her periods take 5 days to end. She had her last date on 21 april. Now the problem is that even after the ending of period she had a little bleeding spots from last 6 days and yesterday bleeding was more than previous days, she is saying may be she had her periods again. So please tell me why is this happening? Is it normal condition or something serious? please suggest me the best advice.
