Could I be pregnant?

[N31kah]

I'm currently nineteen days late and I'm having light brown spotting and about eight days ago I had very light pink spotting (which only lasted two hours). I've done a couple of tests in the last three weeks and it was either negative or invalid but I've been nausea almost every day, light cramping, very moody (apparently), my boobs have been very sore (My partner and my mother both told me they appear to be getting bigger)and I can't stomach certain things recently.
I'm not too sure what to think about what's going on with my body, any opinions or advice?
TIA.

Symptoms of a period starting and pregnancy can be very similar sometimes- so I wouldn't go by the symptoms alone.  Since you are 19 days late, the negative tests should be pretty conclusive, but have you tried a few different brands?  Sometimes you can get false negatives, but it's pretty rare.  With the other symptoms you are having, I would say it doesn't hurt to head to the doctor just for a check up and peace of mind!
