period-like cramps at 28 weeks?

Tabitha • First time mom💘 Baby Zoey due oct 21🕊🎀

anybody else experience mildly painful cramps? localized in your lower back and sides, like a period? I looked it up and some said it's common, while other said it was indicative of preterm labor, so I'm a little worried as a FTM. EDIT: I forgot to mention they're constant since I've woke up, not intermittent
