33 weeks - grinding feeling


I am currently 33 weeks. I go to the doctor again this Friday for a regular check up with my doctor. The last visit she said little man was measuring 3 weeks ahead of what he should be. That he will be around 10 pounds and is still breeched (he still has time to move head down tho so no biggie) BUT today I got SHARP pains really deep down and extremely low (not Braxton Hicks) and it felt as if there was a grinding motion in ever movement I have made - put in a call and message to my doctor as to if this is normal. I’m a first time mom and looking for advice/guidance/peace of mind.

Photo of little man at 28 weeks so this doesn’t get lost.
