Help.. To test or not test

Tiffany
So I have always had a little pudge around my tummy but never as high as it is. I was on the patch up until the end of October! I dont know if this is that or if I should test. I had my period 11/15 and we had sex one time on the most fertile day during that week following the period. I am due for AF 12/14. I haven't had any normal symptoms of pregnancy or anything but I just feel fatter. What do u think ladies???
