Help? (A bit of TMI)

So... honestly can't remember the last time I hooked up with my ex (we are FWB, long story don't ask) and my period was due yesterday. I've been having tummy cramps like a period, but absolutely no bleeding, not even spotting. I just started a new job on the 16th, so I want to say that that's why my period is late... but honestly have no idea. I've also had kinda loose to diarrhea when I go potty. (Sorry for the TMI). I've been eating a lot of chocolate the last 2 months and can't get my sugar craving to go away. (Yeah, horrible timing with holidays). Anyways, has anyone been in this situation and not been pregnant? Or did it turn out that you were pregnant? I've even been wearing pads in hopes of it showing up, but nothing. I have a 15 month old, and live with my dad and stepmom... so I can't have another baby... especially out of wedlock and with my ex. My parents would flip. (We are Christian). They weren't thrilled about my first pregnancy, although they were supportive and adore my son, they keep drilling it into me that I can't handle another baby right now and blah blah blah. Anyways, sorry for the long post. Any suggestions or comfort would be great. And no I'm not taking a test until my period is over a week late because it's been late before and I've not been pregnant. So I am dealing with denial. Lol. Thanks y'all!!
