Spotting at 28 weeks

Emily • Due 10-20-16 with princess Leilani 💖👶🏽
I've been feeling off today. Just not myself, and I just saw a few spots of blood on my underwear and when I wiped. I checked my girls heart rate and it was in the 130s. She's moving, less than normal but she's definitely moving. I'm not really concerned since it's just spotting but at the same time any blood puts me on edge. I'm not really wanting to call L&D just in case it's nothing. Anyone have this?
