Help‼‼

So I had my implant out over a month ago due to it not agreeing with my body. I had it in 1 ½ years. I got put onto the pill and the same day I had my implant out I took a pill and ever since I've not taken them. I've not being seeing anybody but tonight I ended up having sex with my ex (who is also my 4 year olds father) we didnt use protection and I told him I wasnt on anything but towards the end he told me he didnt pull out in time (I know the pull out method doesn't work most of the time btw) so now I'm abit worried incase I'll end up pregnant again. I would love another baby but just not with him and not just yet as I've just got my own place and a stable job. I knew we shouldve used protection at least but when your in the moment it's the last thing on our minds. Please no judging x
