So I came on my period a day earlier than my predicted date (2 days earlier on some apps) it was light to begin with then slightly heavier then tailed off again- lasted my ‘usual’ 5 days but something just felt ‘different’

I finished yesterday properly and I’ve had horrendous lower back pain and low abdominal aches since. Is this normal?!? I thought I was having pregnancy symptoms before I came on so was gutted!!

Can anybody help 😩 I suffer with my back anyway, currently under a chiropractor.

Thanks!
