Hi Doc. I m 29years old I had unprotected sex but I took postnor2 immediately a week later I bleeded for 3day,but ever since then I have been having nausea,weakness of the body,sometimes I feel like vomiting and recently I have been finding it so hard to breath well.I had pt test but negative,I have gone for scanning nothing everything came negative I went for stool test and swab but nothing seems to be wrong,I took malaria any typhoid drug yet I m still sick but could be the problem?does it mean postnor2 is too strong for me cos that was the 1st time I have taken postnor2 in my life.so pls help me out cos I m tired.
