Vagina/cervix pain

I'm 10w6d along. Since last night I've been getting an on and off shooting pain near my vagina/cervix on my left side. It's kind of hard to describe. If i sitting it's like it just on my left side inside of my vagina. Sorry for the vague description. No spotting at all. I've already had two u/s with heartbeat. Doc couldn't find heartbeat with doppler other day, but said that was completely normal and we probably won't find it via doppler until my next appointment at 14 weeks. Is this possibly my just growing pains?
