Sex after birth

So I was cleared by my doctor already, I’ll be five weeks postpartum tomorrow. My SO and I had sex for the first time over the weekend, and he didn’t pull out which isn’t a big deal to us because we know we want more children and for them to be close in age, not necessarily this close but if it happens then it happens (my brother and I are exactly a year apart, our birthdays are 3 days after another). I was just wanting to know with breastfeeding and not having a period yet, what are my chances of getting pregnant this soon? I would be happy if I ended up pregnant again, I actually miss the feeling.. I know it’s not necessarily healthy to get pregnant back to back, but what can you do 🤷🏻‍♀️ no negativity please..
