No period nine months after stopping breastfeeding

[AMinorBird]

I stopped breastfeeding my DD nine months ago when she was 18 months old. I still haven't had a period. Should I worry?

Are you pregnant? I'd probably get checked out at the Gps to be honest

No, sorry, should have said. I am definitely not pregnant. DH had the snip as we're done with kids so I'm not on the pill either.
