Is it safe to masturbate with a toothbrush?

I was getting down to business and got a little carried away and dug out a tooth brush (disinfected it) and went to town. Now I’m having a panic attack that I’m somehow gonna die or become infertile because I used this random ass toothbrush. I checked it after use and it appeared nothing on the toothbrush was missing but I’m still scared something fell off and I’m gonna die of sepsis. It wasn’t inserted very far, maybe only half. I know I shouldn’t have done it but I haven’t masturbated in almost A MONTH and couldn’t help myself. I don’t care if I get a yeast infection or vaginosis because been there done that, but I can’t calm down thinking I’m gonna get sepsis or get seriously ill.
