What type of discharge is this

My period is a week late. My bf and I have had sex twice since I had my last period. We didn’t do it long and he didn’t ejaculate inside me or outside(live with parents still) we have been together for 4 years. My parents know we have sex. I haven’t had any cramping, just normal pms. Headaches. Wanting food, mostly chocolate. Bloating a tiny bit. Crying here and there- like tonight my cat scratched my leg if hurt and I cried. My period has only been late one other time and was last year
