Help PLEASE. I really need some adive. I know I should prob go to the doc but I dont want to go yet not if there isnt any reason to go. what do you guys think??? HELP

It's quite posible you've had some implantation bleeding instead of a period.. Its pretty consistant with the dates you've described.. If you are pregnant or you think you are you ought shuffle off to the doctors to get tested, however in some people you can produce a protien in your blood that acts as a "block" of the hcg hormone necesary to find out your pregnant thru a blood or urine test so if you talk to your doctor and your blood test comes back negative i would think after so long you would be sent for an ultrasound to make sure..
