6 weeks with slight cramping

Hi! FINALLY got my positive results! I have an apt next week for just a blood test to confirm the positive at home! Looking back at my last missed period and such it would put me around 5-6 weeks. But I’ve been having some slight cramping in my lower area. Nothing as bad as period cramps but like an annoying ache I guess you could say. Feels like my hip could be out of place. With my last child I had HORRIBLE round ligament pains and issues- which was 5 years ago. Anyone else have these issues with 6 weeks and slight cramping?
