My period came back (properly) about 18 months after I gave birth.
Since I've had it back (several months), I get light crampy pains in my legs and feel a bit rubbish generally for several days beforehand.
Before I had a baby, it would just be immediately before, if at all.
Does this happen to other people? Will it change again? It's really irking me, actually.
I just remembered I used to get really bad pain when I was in my teens, but it just kept getting better as I got older.
