hun (sorry i dont know your name yet....is it elizabeth, because some people use other names for their display names), you should go check with a doc, 11 days isnt that bad but just to put your mind at ease
and dont feel too bad im in the same boat, my last period was nov 15th and ive had 2 neg hpts also...but then again i just had a baby 7 monthes ago, ingi said its probably hormonal because it can take up to a year for my body to get back to normal, so im gonna wait it out for a few m ore days (i FEEL like its gonna come but then again i felt like that last month) and if it doesnt im gonna go to the doc
good luck
