Freaking out here!

I'm hoping someone is awake to give me a piece of mind or at least help me out here. It's 4:30am where I am and I woke up at 3:30 to go to the bathroom (I'm 13+4 by the way) when I wiped there was quite a bit of pink bleeding and I'm freaking out. I had a miscarriage back in April but I was only 7 weeks at that time. I had a healthy scan at 12 weeks (about a week and a half ago) baby was fine, dancing around had a good heartbeat etc... Now I'm freaking out because I'm scared that something has happened to the baby. Has this happened to anyone else and the baby was ok? I am going to go to the dr in the morning but I just want to know if this has happened to anyone else and everything turned out ok with baby.
