Pelvic pain.😖

I been ttc for 12ms now. I'm just one day late on my period but for the last couple days I've been having cramps on my pelvic area & vaginal area like on my groin. Has anyone experienced this in early pregnancy? I don't want to get my hopes up that's why I haven't tested because I have been late before. My periods are regular but have had a missed period my 3days before. I really hope this is my mouth! Help!!!!😁😐
