2nd time bleeding..HELP

TLeigh4413

a week ago I woke up and took a shower to find that I was spotting a little. It was a little red but kinda had some pink in it too. I had cramps along with all of this as well. I went straight to the doctor. They did a sono first before seeing doctor and saw baby with great fast heart beat. Doctor said it was implantation bleeding and come back in 3dys for repeat check up. Went in 3days later, everything was still fine, saw baby heard heart beat and told to go back to normal activity. Bleeding stopped 2days later. Well, woke up this morning, getting out of the shower noticied pinkish/brown stuff coming out of me. Called the doctor he is out on vacation. Nurse said it was probably fine. My cramps are not that bad. WHAT SHOULD I DO? Has anyone else had the same?
