pain after sex?

i recently had sex again for the first time in roughly a year, and everything was fine until about a day later where even just standing, my vagina would hurt. Yes when i go to the toilet it does too but it’s not even a burning feeling it’s just a lot of pressure. it’s just super uncomfortable and i’m not sure if anyone else has been through this but i was just wondering if i should wait it out or go to a doctor ? any help is appreciated x
