12 days late followed by 3 days of bleeding, experiencing some symptoms

Can someone help. My period was 12 days late and then I had a very faint postive pregnancy test. This was followed by 3 days of bleeding-light day 1, on day two heavier, but only 1 or 2 pads in 24 hours, and day 3 light. I am feeling achy, tired, moody,and my breasts hurt-what do you think?

i was 13 days late and had a light period for 3 days and its days FIVE and im getting a brown discharge when i wipe
i went to the doc because ive been nauseous for a good 3 1/2 weeks and tired sore and having an ncomfortable feeling in my stomache thats painful sometimes.
i went to the doc about 2 weeks ago and he did a urine test that said i was NOT preg.
but i wasnt even late for my period yet.
so im still curious as to whats going on!
when you find out whats going on with you keep me posted.
because sounds like you and i are in the same boat.
