Burning before period

This is weird but just curious if anyone else experiences this as well! 4-6 days before my period starts (usually on cycle day 19 or 21 of a 24-26 day cycle), I get this burning pain on and off. It’s not really painful, just annoying. It comes and goes throughout the day- never a constant pain. I’ve had it for years, this is how I always knew that my period would start within the week before I started tracking it! I’m pretty sure it’s just related to hormones dropping right before my period starts. But does anyone else experience this as well? 😅
