Advice pls!

So I'm due for my period today and haven't started, well on the 30th of nov (three days before my period supposed to start.) I had a crazy dream that I was in school and had my head down and minutes later ended up throwing up in my dream well the throw up was pink? Well when I woke up I ended up running to the bathroom to throw up I only threw up once and have only had some nausea since but here is today and I'm supposed to be on my period and nothing has happened yet. Also my belly feels bloated just in my lower abdomen and I could of sworn I felt something when I pushed on my left side and when I brought it to my husbands attention he said that my left lower abdomen looks bigger, so i guess my question is an I pregnant? Has anyone else ever experienced anything like his before finding out u were pregnant?
