I do need some support on this, I'm scared and worried....

Last week me and my boyfriend had sex and one lead to another and he cummed me (4times) it wasn't planned but we have deep feelings for one another. We started dating like last week so we're new and now looking back I feel like I might made mistake, not because what we did as much as my parents and my friends are going give me the rushing talk and I'm not knocking them don't but it doesn't help and instead makes me feel all these negative emotions 😔 we both have jobs and I'm planning on moving in with him, he has his own place. We are planning on keeping it but will find out the truth on 13th that will be date if I miss my monthly.

I don't know what I'm asking just support or help or whatever. I'm staying anonymous because I'm just to scared to show my face
