Yes, I have had it for two weeks now, off and on. I am not 7w4d. I have read up on it too and I have come to the conclusion that its RLP? Round ligament pain normally happens in the 2nd rimester from what I read, but there are a lot of people that have it in the first trimester.
Hope your doesn't last too long! It can be a sharp pain every once in a while for me. Doc says everything is fine.
