threatened miscarriage ??

Jemma
Hello lovely ladies. I am 5 weeks pregnant and in the early hours of Thursday morning I woke up with period like cramps,I went to the toilet and saw that I was also bleeding. (Bright red blood) 
I went to see my GP first thing Friday morning and she has said that its a threatened miscarriage. Today ( Friday ) the bleeding is a lot lighter and the cramps have almost gone. Has anyone else had a threatened miscarriage and gone on to have a successful pregnency?
