Early labour?

Charlotte • Became a mum on July 3rd 2018 👶🏻❤️

Lost my mucus plug yesterday, over night I woke a few times with pressure and period pains.

From 03:30 (uk time) until 06:00 have lower back pain and period like cramps every 7minutes lasting 30-40 seconds..

seems to be fading now though 😩

What could this be?
