Bleeding in first trimester

Autumn
After trying for 7 months my husband and I finally found out four days ago after doing home pregnancy tests that we are pregnant! We've been so happy and my first appointment is in a week! However, this morning when I woke up I was bleeding bright red blood and it scared me to death! I'm not cramping really bad, like no here near how I cramp during a menstural cycle and I'm not bleeding heavy at all! I've not even needed to use a pad! Has anyone else experienced this? Is it normal to bleed a little bit in the first trimester?
