Help!!

Soooo... My SO and I decided to start trying for a baby. I am now 3 days (technically) late for my period. I usually start having cramps 2-4 days before my period even starts. NO SIGN of cramps or a period so far. BUT I have a lot of white discharge. No odor or anything just creamy and white/clear. (Sorry, TMI.) I also have been having achy boobs and little bumps on my face but I usually have very clear skin. I have taken pregnancy test the last two mornings and Negative :( Can I still be pregnant buttits too early on the test maybe? Advice??
