I ended up in the Emergency room Friday night experiencing sever abdominal pain so they of course did a pregnancy test and it was negative. I am experiencing all the symptoms for my period but it isn’t coming. I asked my doctor about if it could of been the medication they administered to me but he said all they gave me was dosages of tortadol ( strong ibuprofen)and nausea medication along with buscopan which is a muscle relaxer. I am now 4 days late having terrible cramps and pelvic pain. Not sure what to do anymore.
