A little confused.

Hi, its my first time posting anything . :-) ima a mom to a 6 yr old daughter and an angel baby i lost Nov.2013 due to ectopic. I also lost my left fallopian tube. To keep.this short and simple. Last period was nov 30th unil the 5th of december. I am late and havent seen any period yet! I have slight cramps,extremely sore boobs, nausea and fatigue. I had no clue i was prego the first two times. But these symptoms have me wondering if maybe there is a baby Any thoughts or opinions?
