hi there! we got the same problem of missed period, but mine was a week or two weeks late. i should have had my period last January 25, but it did not came..feb2, i got little signs of blood until feb 5. but not as normal flow of my previous menstruation. i took a pregnancy test feb 7 and the result is negative then again by feb. 13 still negative,,, its already 2 weeks and i guess, to take awy my doubts.. i would still be having a pt on the 21st... if its negative again, maybe i have hormonal imbalance, and have to see the doctor... this also happened before. and i was so scared because Im not ready to have another child yet. i looked for possible answers to my questions, and some site said that misse dperiod could be due to stress or having a big event in your life (vacation, changing environment) and most especially if you are stressed and worrying.
