Ok so I was suppose to start my period on the 18th but started the 16th I felt fine til I noticed I started and it was dark brown that turned into red blood it was heavy that evening into the next day the 17th. Later that evening it started getting less like pinkish brown kinda spotting. On the 18th I had this

That morning I had a glob like that in my pad then I get that about two hours later. I was cramping bad to but not to bad. Later that day it’s gone I spotted brown then nothing. Next day I very light spotted nothing serious then on the 19th nothing but still cramping lower back pain and hip pain the 20th spotting started up again nothing serious then cramping back pain and hip pain I even felt bubbles in my uterus area that was weird now I had this

I’m still having cramping lower back pain and hip pain. Is this just a weird period for me or something wrong. Like I even had a embryo cloud and egg yolk two weeks ago.
