Tons of discharge

My period is due in five days and for the last two, my uterus has been very sore and tender. Then today, I’m having a lot of discharge. Like A LOT. It’s creamy and white/pale yellowish. I didn’t have this with my other pregnancy until much later (maybe ten weeks), and I don’t have this much normally at this point in my cycle.

Anyone have this and turned out to be pregnant? Or maybe this is just a new weird PMS symptom for me??
