Could i be pregnant? Would really love some opinions. Thanks(:?

I have currently missed my period for this month, and me and my fiance' had unprotected sex before and after my period, and all of this month. I've been having to pee alot more than usual, I've also been eating way more and craving foods. I've been having a sharp kinda stinging pain on both my right and left side it comes and goes. I didn't really get all of these symptoms with my 2 year old daughter.. So i was just wanting to know if anyone else has done this way? Thank you everyone!
