Need some reassurance...

So, I lost my new packet of B.C. pills... I know already off on the wrong foot with that line, but I decided may give my system a flush and restart the next month when I finish my period. So, my boyfriend and I had sex and we did NOT use protection, another big WTF already, I looked up when I was supposed to ovulate and I was already on my fertile week. and the next day I ovulated. Today I was supposed to start, but it hasn't came yet, but I have the symptoms! Should I give it a few more days before I take a pregnancy test or should I take one in the morning, if I haven't started by then?

Side Note:

If we found out if we were pregnant, we would be thrilled but scared. So, I know I was not using my head when it came to this, but that doesn't mean we wouldn't be happy or feel blessed. So please, no negative comments.. Thank you in advance.
