Help?!

I am 7 days late.. Having slight cramps and clear (no odor) discharge.. I'm usually not late and if I am it's only a day or two.. I tested and it was negative.. Friends and family say it could still be too soon.. (Mother didn't know until 3 months) (mother in law didn't know until 2 weeks after missed period) my breast feel heavy and kinda tender.. I'm sleepy often.. Appetites kinda back and forth.. Just odd feeling and not sleeping good at night!. No spotting or anything.. There was some very light spotting when I wiped about two weeks ago..
Any suggestions?! Please
