Pain When sneezing !

Ashley • First time mom living in Miami waiting for my baby boy due in April 2016
I woke up in the middle of the night & sneezed a few time I got this sudden sharp pain just for a few seconds ? Is it normal can it be round ligament pain ? I'm 19 weeks & 5 days this is my first pregnancy so every little thing worries me ! Should I go to the doctor or is this normal
