I’m scared I might be pregnant😭

I’m 15 years old and I’m on Birth control. I was on the pill and took my pills late sometimes or even forgot to take them some days. I went camping in January with my boyfriend and some friends. We had unprotected sex and he came inside me, that was around the time I took my pills late a lot and forgot to take them sometimes. I have been taking a lot of naps lately( I used to take naps all the time but I stopped and now I started again) I feel like I’ve been eating more, I have been having a sore back( I also kinda slouch a lot so idk if that might be the reason) I have kind of been getting little headaches but I have never had one before so I’m not sure if they’re actually head aches. I’m going to text out public health nurse tomorrow and ask her if she can give me a pregnancy test and I

Hope it’s come back negative, I’m way too young. I want to have kids in the future with the guy I’m in love with rn but we agreed not till we are older and I’m so scared I might be.

UPDATE: I’m not sure if I’ve been getting my period or if it’s just been spotting cause it’s not very consistent. The app says I am supposed to get it today

And I love in a small town that does not have a planned parenthood place but we have a public health nurse to go talk to about this stuff and I texted her today but she hasn’t responded

And I’m too scared to tell my boyfriend about all of this. Cause I know he wants to have kids with me but I know I’m not gonna have a kid right now. Should I wait till I get a test and see what happens or should I tell him now? I don’t wanna worry him too much.
