Pregnant...? i would like a few opinions or some thoughts!?

I just started taking the patch the first day i got my period on dec 31st. i took it perfectly until dec 11 when i had an allergic reaction to it and had to take it off. i heard the hormones stay in your body for a long time so i cont to have unprotected from dec 11th until lastnight. i had withdrawl bleeding from dec 12th to dec 16th. My period is supposed to be due today, i havent gotten it yet...i have slight cramping, very sleepy, and very wet ( sorry tmi) as well as sore to the touch. I'm not sure if i had gotton preg, or the hormones are just messing me up but i would love to here some opinions..thanks!
