Slight bleeding?

wi

I'm 16w5d and had my regular appointment today. No internal exam or anything but I've noticed the last 2 times I've gone to the bathroom, just a hint of blood when I wipe. I had an ultrasound today and they said baby looked good with a heart rate of 153. I'm having an internal freak out but trying to tell myself everything is fine. I literally saw baby today but can't seem to calm my brain.
