Help me

Yesterday I had sex without condom and when my boyfriend told me I’m cumming I was late to move for 1 second and when I looked he cummed without playing it and I’m really nervous because I’m afraid that he cummed inside me. I asked him but he told me that he is sure that he cummed outside and that I have no reason to be afraid. From yesterday I sweared that I will not have sex without condom again. Should I take the next days pill ? The last time I took the pill was at March and April

What should I do ???
