10 weeks, achey and spotting. normal? anyone else?

Bethany
I woke up this morn. Had light pink spotting once, now it's brown every now and then. My lower abdomen/uterus is achey. Not really cramping. I called the doc, they didn't really help any. I had an ultrasound 2 weeks ago and the baby's heartbeat was strong and he/she was wiggling around. Has anyone had his at 10 weeks since I can't really get answers from the doctor. 🙄😒 thanks!
