Body malfunction...

So last month my cycle was a little strange, 2 days early with just spotting, then 2 regular days, then 2 more days of spotting(cycle is usually 4 days) . Now on to this month, AF is not due until 16th I have been slightly cramping this week like my cycle is getting ready to start, a little nauseous and 2 seperate days when I used the restroom and wiped (sorry for the TMI) I noticed a pinkish tint also some pain on my sides, mostly on my left side. (Not Ovulation pain) Trying not to get my hopes up again, been trying for 11 months. Should I run out and get a pregnancy test now our wait till Tuesday for AF?
