Chances of pregnancy?

So, I had nexplanon for just over a year since having my daughter and due to soooo many issues I had it removed on the 3rd of February. I don't know when my last period was but I think it was maybe the 13th of January. Anyway, I had clear stretchy cm on Monday and Tuesday had the most amaaaazing sex but we didn't use anything 😐 now im not sure what the chances of getting pregnant are. Has anyone got pregnant straight after getting off nexplanon?
