TMI spotting

I have been spotting off and on for the last two weeks (I’m 6 weeks 3 days today). Today the spotting is a bit heavier and darker than I remember but not enough to even get any on my underwear. Anyways, this is my second pregnancy and I’m praying that it sticks. I have no cramping, just increased nausea. Anyone ever had this? What kind of outcomes did you have? I have an ultrasound Thursday. I’ll keep this updated.
