Advice?

I’m only 6 DPO but I’ve been having weird symptoms. Did anybody symptoms start super early? I had the worst cramp of my life a couple days ago in lower abdomen then it switched to my left side and i literally couldn’t move! My nipples are really sensitive to touch only nipples though i haven’t really given any attention to my boobs and I’ve been constipated for days. I know it’s super early but every female body is different. I just want to know did anyone experience any one of these? Or early symptoms? Please help!
