Is it normal to have blood on your stool?!

I am 13 weeks and for the past 2 months I have noticed randomly that there is bright red blood present either on tissue or in the bowl. I spoke to my sister and she said that it is hemroids. Say what?! I don't feel any discomfort and I'm pretty regular and eat well. I am planning on speaking to my dr. But have been able to make appt today. Just wondering if this is normal at this stage in the game? Should I be freaking out?
