Started this afternoon. I moved in my seat and I had a pain in my uterus area where I usually feel menstral cramps, went to the bathroom a bit later and there was a little bit of pink on my underwear and the toilet paper when I wiped. Saw a little more when I went again later today and have been cramping on and off most of the day. I am 8 weeks and 1 day and my first dr appt is tuesday.  I've read that it's normal but I'm still freaking out and super stressed right now, I didn't have this with my first.
