Period or implantation?

I think it’s my period about to start because I’m due to start that between today and Monday. I’m 12DPO. Since I’m wearing dark colored underwear today I decided to put a pad on so I could see the coloring better if I had more. Last night around 11:30pm when I wiped, I had some colored discharge (no picture). When I went to the restroom later, I didn’t have anything when I wiped. This AM, I was watery pink discharge both times when I went. Now I have this. Do y’all think I’m starting my period?
