HELP ASAP

(I AM A FEMALE) I recently had sex for the first time and at first it was painful then it started feeling better but it still kind of hurt. After a while, I started getting a type of suction cup feeling like my vagina would grip onto him and it didn't necessarily hurt but it felt really weird. He would take breaks and cuddle with me for a bit then go at it again. It's been about 13 hours since it's happened and I'm extremely sore and my vagina hurts. I looked in the mirror to make sure I wasn't bleeding and I spotted a purple-ish red lumpy ball inside of my vagina so I immediately googled it and the best answer was that it was my cervix. However, if it is my cervix it's extremely low. This may sound disgusting but I'm just really worried and confused.
