My period is do on the first every mouth today is the 17 in still no period.I have cramping feeling in stomach pains what should I do? I went to the dr but it was negative

Stress, illness, diet/weight change, etc. can delay ovulation, therefore your period.

If you have cramps, I would bet your period will be following soon after. If it doesn't come for two more weeks, test again.

My period did not come on for March today is April 1, 2010 in still no period I had cramping but still no period. I took three pg test in all came out negative so can someone help me on this one
