Possible Pregnancy

Ju
So im officially two weeks late. I took 3 tests 4 days ago all were negative. I dont have morning sickness or sore breasts. But I wake up with a small headache almost every morning, my breasts feel bigger, I use the restroom more often and I've had mood swings. Im planning a wedding so I might just be stressed. Also we always use the pull out method. Does this sound like im possibly pregnant?
