Round ligament pain (or something like it) before bfp

Ma

I am 6 to 7 dpo and I have been having cramps and had little pain like round ligament pain. I have only experienced this feeling in pregnancy. If I am pregnant this would be my 6th pregnancy. I have three angels and 2 rainbows. Has anyone ever experienced this? I feel like I am crazy but I have read it is possible?
