Is it bad if he didn't kiss me goodbye?

been hanging out w this boy for like 3 months off and on, its casual- no sex just mostly kissing and some other stuff. he texted me to ask what I was doing this past weekend and said if I decided to go out to let him know. long story short we ended up at same party and he invited me back to his house to sleepover. we hooked up but nothing more cause I had my period for like the 100th time when I was hanging out with him. everything was good until next morning it was kinda awkward when he dropped me off and he didn't kiss me goodbye. He's kissed me goodbye every other time but this is the first time we ever did a sleepover. is this bad?
