Done Fucked up I believe ...

So I was having sex with my lover we used a condom and the condom broke we didn’t realize it til it was over and he already had ejaculated I just recently had s baby 3 months ago and didn’t get on any form of birth control cause we were completely being safe. So that was last Thursday so chances of getting pregnant again ? Also I was going to take a plan b but I didn’t have enough money because i had to pay bills etc etc etc
