TMI* but I need advice

I'm 8dpo and my husband and I TTC this month and now I am experiencing a few things that are different. Today I just noticed a white creamy CM and I am experiencing mild cramping on my left and occasionally right ovaries. I'm also having some lower back pain and sometimes a weird sensation in my boobs. I also have been getting a weird metal taste in my mouth. I'm also bloated and af isn't supposed to come until the 24th or 25th.
