Freaking out teen!!

Okay so before I get bashed about not doing my research on Safe Sex, I promise i have done TONS of research on Sex. But I do have a question that Google is not very helpful with. So me and my boyfriend were messing around as per usual, well this occurring time i let him slip it in, I am and have been on The depo shot for a year now, and he did not cum in me. He was only in a couple times but not deep. I have a concern he precumed in me...When he pulled out, He precumed right then. But Im afraid he did while he was in me. Is there any possible chance I could be pregnant? Anything would be appreciated ❤️❤️
