SOMEBODY! ANYBODY! PLEASE!

I am on cycle day 58 and my period still has not come. For the past 3 weeks I was cramping non-stop. Feeling nauseated, hot flashes, kind of constipated. I have taken 3 hpt they have all been negative. Gas cramps are horrible and this little headache I get in between my eyes and nose is annoying. Can anyone give me some advice on what to do. Has anyone else experienced this. I have been taking geritol for a little while now and we never have protected sex. SOMEONE HELP ME PLEASE
