Not by the textbook

Nathalia
I have been off birthcontrol for a few weeks now(after being on it for 8yrs) my partner and i baby dance a lot... and not based on any schedule or anything specific.
I do not have any "textbook" symptoms of pregnancy, but i have PMS symptoms with no blood. I spotted one time after sex and that was a light pink. 
Im not throwing up, nor are my breat tender. 
So is it even worth the money to get a pregnancy test?? Or is it just my body getting back to normal from letting go of the birthcontrol??
