Yes I get them if I sneeze suddenly or stand up too fast. Basically anytime I use my core muscles too quickly I get it for a few seconds and it's painful! I'm 9w2d today
I also have never heard of round legamnet pain, not even a phonetic equivalent. Maybe OP is not a native English speaker? I agree with @emilyzemily who referred you to the symptoms thread.
