Advice! Might be TMI for some.

So I know it's only 2 days sense I missed AF, but if I still don't get it, when is an ok time to take a pregnancy test. I spotted a little the fist day I was supposed to start but haven't sense. Not getting any of my normal PMS symptoms and I've only been maybe 2 times in the 4 years I have been with my fiancé. I don't want to get to excited and jump the gun! Any advice would be GREATLY appreciated!
