Pain and bleeding during sex?

Me and my boyfriend recently started having sex after my four years of celibacy. I am not someone who has ever been to the obgyn but I am considering go for this specific issue.

We were having sex tonight and we tried a new position. We typically do missionary but I sometimes get in pain (I assume my cervix) from trying it doggy or any other position. This is sort of like missionary but my legs are on his shoulders. It was a little painful but it felt really good so I didn’t think much of it. 30 minutes in he takes a per break and turns the light on. I look at the condom and there’s dried blood on it. I then look and my hands and my stomach and there’s a bit of blood too. I told him and we didn’t care so we continued. This sort of reminds me that I got a dildo (CELIBACY WAS HARD) that was no more then 6 inches and I bled on it multiple times. Is this bad?
