Spotting at 5 weeks 5 days

So I started spotting yesterday freaked me out they got me in to test my levels but it's the first blood draw I've had this pregnancy. I'm so nervous because I've had a molar pregnancy before I had my son. It's not a whole lot now and it's going between pink to brown starts out pink in the morning turns to brown the later in the day it gets this is the second day of the spotting. I haven't had any cramps or dizziness or anything that would suggest miscarriage but I can't shake the feeling looking for reassurance. I do still have sore tender breasts and I'm still bloat and gassy which explains any minor cramps I do have they are the bloaty kind. Anyone else have this problem? My base line hcg level was 6947
