TMI cramping in strange places!

Last couple of days I have been experiencing weird like pain/cramping in essentially my vagina and what feels like my bottom too! I've been off the pill for a couple of months now but not had a full blown AF yet and am wondering if it's my body gearing up for it! Been on the pill so long I can't remember what a real AF feels like! Any thoughts/experiences with this sort of thing would be appreciated! Just would like to know if it's just me or others get this too! Thank you in advance! Xx
