Symptoms/spotting

Hello ladies...periods due Friday 10/25. I have been having light cramping on and off and my breast have been a little sore. I have been nauseous in the morning and sometimes when I eat. I have had lite spotting when I wipe since Thursday. Very small amounts. once was pink all other times brown. No panty liner needed as it only happens when I wipe.

Thoughts as to what this could be. Could this be implantation bleeding? I know it’s too early to test.

Thanks in advance and baby dust to all!!
