I'm I pregnant......?

I had unprotected about 2 weeks ago today and was during my most fertile day according to my ovulation calendar....my period was due today and hasn't arrived yet....should i give it a few more days to see if Aunt Flo starts???? Or should I take a pg test soon? I have this weird type cramps that come and go they are not like period cramps though and my have felt achy off and on...moodiness and fatigued too a little bit...let me know your opinions guys..it is greatly a apperciated...25 years old so I do already know consequences of unprotected no lectures just advice/opinion....
