Spotting 6 weeks

Lori
Hey y'all! I started spotting this morning like brownish pink I'm 6 weeks 1 day. I called my doctors office and they had me come in for blood work to check my levels and I need to go back in two days for follow up blood work to double check the numbers again! I'm hoping everything is okay. I haven't had an ultrasound yet or anything so I'm nervous now! Anyone else experience this?
