Implantation bleeding

I’ve been getting some light cramps for about a week now and they are weird feeling it doesn’t feel as cramp like more like muscle pulling. Then today I started getting really watery discharge that was pink and kinda mucus like. It went on for and hour or so and I thought it was my period but after around 2 hours it just stopped. I’ve never had this happen when I am on my period. Can someone please help?
