Could i still be pregnant?

Aylin

I have been having pregnancy symptoms for the past few days, and yesterday and this morning i took the extra sensitive pregnancy test (10miu)

Both negative. However my period is not due till jan 1, could i have ovulated later than i thought and still be pregnant?

Also just a lil bit ago i went to the bathroom and as i was cleaning i noticed this, my boobs feel sore and i have cramps.
