am I pregnant

I am late for my period for 1 week and 4 days, I've had irregular cycles before. My breast and nipples have been tender and sore for almost 2 weeks now. my aereolas have also increased in size and gotten darker. I don't know what dpo I am because I lost track I've experienced nausea for a week and I have left side pains, bloating, back pain, hot flashes, metal taste in mouth I've had negative hpt using the brand healthy wiser i just need some advice. I'm going to keep testing in a few days I may even set a doctors appointment. anyone else experienced this. I also got off of my birth control in November.
