Sex pains

So my boyfriend and I have been trying to have sex for a month now. It hurts me when he puts it in but he finally got it in. But it’s been a week or so since we’ve had sex and everytime we’ve tried it always hurts something on the left side of my labia. And it hurts inside on the left too. And when he touches the outside of my hole on the left I don’t feel it but I do on the right. But I feel everything when he fingers me. What do I do? I’m scaring myself and afraid to go the doctors or even ask my mom if I can make the appointment at 19 years old
