I forgot what PMS feels like

So I have forgotten what PMS feels like but I think in going through it. AF hasn't been around since before I got pregnant so October 2011. For the past two days I've been so bloated. I'm talking first tri bloat were I even look pregnant. And I'm tired, cranky, and what tipped me off that this could be PMS I have been spotting a little on toilet paper. I feel dumb but this is prob PMS right, haha! I'm scared if two things: I'm going to start my period and not know it and look like a Friday the 13th movie or I'm pregnant as these were my symptoms before. Ugg. I haven't missed this at all.
