Is Blood Along With Stool During Pregnancy Normal?

Hi. I am in my first trimester of pregnancy, and last night I awoke with some pretty bad cramps. They felt like dehydration cramps, or just that I needed to go to the bathroom really bad. Nothing was coming out right away, but I started to feel faint and had to sit down on the floor a couple of times, and also felt nausea. I drank some sips of water, and broke out into a cold sweat after the faintness passed. Then I finally was able to pass my stools, and had some of the worst diarrhea I ve ever had. I drank some more water and went back to sleep. This morning when I woke up, I felt I needed to poop again, and liquid spurted out into the toilet, that I discovered was blood when I looked into the toilet. I ve gone a few times since then, and the bloodiness seems to be lessening, getting pinker, not as much, etc, but feels kind of bubbly when I am pushing out. My rectum does not hurt, I am not aware of a hemmhroid or tear.... Does this sound serious, or can I wait a bit to see how I feel in a few hours?
