I was very scared with this pregnancy as well! I had a MC last April, and I thought it was happeneing all over again, because I was having cramps in my stomach/lower back. But everything was fine with my baby! I am currently going on 13 weeks tomorrow! So yes, it can be completely normal ...now if you start bleeding heavily then I would be worried...(following with the cramps)....
But yet, I had 3 episodes already of bleeding/spotting, along with some mild cramps. Went in for an vag. ultrasound and my babys hb was really good! Then went back in 2 weeks later for the same reason, and the baby grew a lot!! Now his/her hb is in the 160's!! Best of luck to you!
