Pregnancy symptoms?

I have been off birth control for about two months now. Right after my feral window ended about 2 weeks ago, my bf and I had sex using the pull out method. I went to the bathroom right after and noticed I had really sticky discharge. The sticky discharge continued for a few days and stopped before I was suppose to get my period. My cycles are usually 26 days, on day 24 of my cycle I had VERY light spotting and light cramps, I am now on day 30 with no period and no cramps, and sore nipples. Could I be pregnant, or should I wait a little longer to test?
