Spotting after fetal Doppler

Brittany
I used my fetal Doppler and found baby's heartbeat today but I'm only 10 weeks 3 days so I had to press pretty hard to find it. Literally right after this I had some brown spotting and slight twinging cramps. I was wondering if anyone else has had this happen?  I for sure won't be using the Doppler again for a while just in case.
