Checking cervix and pain?

Meg • 🍍
Hi ladies. I'm at cycle day 28, 14 dpo. I've been checking my cervix a lot lately (AF due tomorrow) and lately, when I do, my canal walls HURT after, something they've never done before. With my longest pregnancy (lost at 9 weeks) I remember getting "tighter" down there, which is what this feels like. Is this a good sign? Or should I get checked out?
