8 weeks & red spotting! :(

Hey guys,

So I'm about 8 weeks pregnant and I began spotting today. It started brown and then red with a few clots. It hasn't been a whole lot, just streaks of red when I wipe after peeing.

My hCG levels are 5500 but I have to wait until the morning for ultrasound...so worried I am having a miscarriage.

Has anyone else experienced this and gone on to have a healthy pregnancy?
