Back ache, cramps & spotting at 4/5dpo

Laurie

Hi ladies. I’m currently 4/5dpo. My last period was really strange. I’m usually on for around 6/7 days. It was heavy but lighter than normal.. on the 4th day my bleeding completely stopped then resumed the next day.

I’m currently 4/5 dpo and I’ve got such bad back ache, slightly spotting (pictured below), I’ve got period like cramps on and off.. what do you think??
