Cervical change??

HI everyone, I am 8 dpo and have been feeling pregnant. I know it's early, but I am extremely in tune with my body. Just did my cervical check and yesterday my cervix was medium, hard and closed. Today it is high, soft, closed and facing the back. Hasn't been that way since my last pregnancy. I have creamy cervical mucus, but also during my check got a string of snot like substance. In my last pregnancy, this snotty stuff was my mucus plug coming in. This would be baby 3 for us. Any thoughts?
