Left sided lower back pain?

I am having tugging feelings in my pelvic area on my left. It also is causing left sided lower back pain. It’s not severe but not mild. It hurts. I’m 9-11 dpo. I use different apps. I’m either 2-5 days depending out from AF. Is this normal for anyone for PMS and periods or for pregnancy? It is not ovulation. Has anyone else had this? What is it? Is Aunt Flo coming? I hope not. Not just cause I’m TTC but also NYE! My luck!

Test is BFN yesterday

Also nausea real bad, dizzy and lightheaded, sore boobs big time starting today (normal PMS), feels like lots of discharge, headache, massive indigestion (not normal at all). Feel cold coming on some and full body aches for days.
