Possibly early pregnancy signs?

Ashley • First baby due 2/2/17!!!
Hi ladies I'm only like 4-5 dpo. AF due 6/1. I've been experience cramps the last few days as well as lower back pain. Also the last two days I've been having very watery CM. so much so I need to run to the bathroom because it feels like it keeps coming out. Never experienced this before. Any of you had these signs and ended up being pregnant???
