I’ve always had regular periods, could pinpoint when I’d start down to the minute pretty much. Came back on my period exactly 4 weeks after giving birth despite ebf 
The last 4/5 have just been really weird. Extreme cramping which is not normal for me, but with a really light period lasting 3 days max. They’re usually quite heavy and last 5/6 days. Also completely haywire, 3 weeks in between, then 6 weeks, then 3 weeks again etc.
I’m on 31 so I’m hoping it’s not menopausal related! But not sure if it’s even worth going to the drs about? Anyone shed any light?
