I agree with these ladies, call your ob. I had a lot of sharp puns in my last pregnancy, found out it was due to a small 1cm fibroid that grew while I was preggo to the size of a lemon. Always good to talk to your ob and get checked if it doesn't go away. Hope you feel better soon!
Definitely call your ob. Better safe than sorry.
If it's not going away and concerning you call your ob. Never hurts to talk to someone.
