Fingering on period

Last night my boyfriend and I were making out and he wanted to finger me but I’m finishing up my period and I warned him twice and he said it was okay. I was barely bleeding but my vagina still had the “period” smell. We’re both 23, but we want to take things slow and this was the first time we have done something sexual. He rubbed my clit and I told him to finger me so he did, then when he pulled his finger out I could smell my gross blood and sweat all mixed together and it was so embarrassing. I told him I had to pee but I let him go first and he was in there scrubbing his hand for what felt like forever. I’m so embarrassed. I hope he doesn’t think I always smell like that. Should I say something to him or just let him wait till next time?
