I have always had normal and regular periods no matter what. The only time I ever missed was when I found out I was pregnant with my first child. We have been trying to have another baby and my period was due dec15th and I still haven't gotten it but my pregnancy test I took this morning said negative. Please help.

A false negative is more common but a morning test should be fairly good at this point but wait one more week and try again, some women test positive latter at times, If still showing negative you can wait to see if you get the period next month and if not see your doctor
