Advice Please

I am #8dpo and I’ve been having more discharge now then I ever get when I’m normally coming on my cycle. I have a lot of cramps and lower back pain, a lot of sleeping, waking in the middle of the night, bloated, discomfort, tingly feelings in vagina sometimes, sometimes my right nipple will hurt, gassy/ a lot of belching, and recently started having weird smells and taste. Some of the things I normally would eat are either tasting weird or smelling weird to me. Could this be a good sign to pregnancy ?
