Mirena removal question

Soo I had mine removed exactly one week ago , they didnt give me much info after like when I’d be able to get pregnant again . Me and my fiancé just got cought up in the moment and he came in me I dnt mind getting pregnant but I haven’t even had a per actually havent had one since I had my son 2 yrs ago , and with him we tried for 18m almost everyday but because I was on the depo shot it messed me up . So I don’t know how easy it is to get preg should I be worried or is there low possibility I’m fertile by now ? 🤔🤔🤔
