Did my hymen break?

Before I had sex for the first time with my boyfriend I used a dildo to get used to the size and feel. Well I'd used a dildo a few years ago when I was a teen and I never had any bleeding from a hymen breaking so just sort of assumed I never had a hymen in the first place. But this time I guess I pushed the dildo in quite deep and after I orgasmed I went to the toilet and there was some bright red blood on the paper. Just a one off thing. I wondered if maybe it was actually my hymen or maybe I was a bit aggressive and unknowingly ruptured a blood vessel, or even if the Nexplanon I got recently somehow contributed. What do you think?
