Not June baby related

My period is about to be 9 days late. I tested on the 18th when my period was 3 days late but it was negative. I’ll post a picture of it. But anyways now I’m starting to get symptoms like I had in my first pregnancy. Arms & legs aching really bad and now my lower back is starting to hurt. Having cramps like no other like my period is trying to come for a few days now. Every now and then when I wipe there is like little brown spots on my toilet paper. What do you’ll think?
