TMI!!TMI!!

So I woke up this morning at 8am feeling supper nauseous and like gassy I went to the restroom and I had diarrea i threw everthing i ate last night up.I haven't ate yet just some crackers and cookie and I've had diarrea like 5/6 times since this morning and it's coming out like water. I don't feel sick no fever and my belly doesn't hurt .....I'm starting to have more and more pr3ssure when I use the restroom and kinda hurts.(could I be sick? Or is this my baby getting ready for the big day!?)
