Need advice asap

So, some background:

-The past month and a half has been extremely stressful for me with my whole moving-out-of-the-house ordeal.

-I had protected sex last week or so, be it was twice in a day and he put a condom on right after he came in the first one.

I usually get PMS a week before my period, and my period is due today. However, I only had something like my PMS yesterday and ONLY yesterday. My breasts were sore and my mood was all over the place but today I woke up and those symptoms were completely gone. This has NEVER happened to me before and Im freaking out. My period is due today and its not here. I have no symptoms of it coming either.

Is it possible that I'm pregnant?? Im waiting a week before I take a test, but Im really hoping Im not pregnant. Im in no position to have a baby right now, especially since I just had surgery on my pelvis.
