Had some bleeding today

So I’m 8 weeks 4 days today. Starting last night I had this pain on the right side low that shoots into my thigh. It continued today so I called the doctor. They had me come in. He thinks its a stretching pain (yes, already!) But during his exam (poked around outside then felt the cervix) I started bleeding. He had me do an ultrasound and baby had a strong heartbeat and was moving the little arm nubs a bit. He said that technically with the bleeding, it’s considered a threatened miscarriage but that chances are low based on the ultrasound results. He thinks maybe the cervix just got irritated with the exam. Anyone had this happen before?
