Feels like I'm in my period with no blood

Cassi

AF isn't due for another 6 days and I'm usually every 28 days like clockwork. Having lower back pain and a bloating/ heaviness feeling by my uterus/ ovary area. Had some pinching feelings on my left side a few days ago there's also a warmth that comes and goes around my uterus.

Don't know if my period is coming early or??? Maybe 👶?

Insight anyone?
