Cramping?

Jamie • Expecting baby #1 March 24, 2018!! Firefighter 👩‍🚒 EMT 🚨 Couldn't ask for a better husband!!

I'm just bearly 4 weeks but still having very small sharp pains in my lower abdomen. They are noticeable but don't really hurt. Just feels like small pricks. Is this normal or should I call the doctor?
