Help

So baby girl is 2 weeks old today and I know it’s recommend to wait 6 weeks before having sex postpartum but I didn’t have any tears or stitches and felt ready. We used a condom but once removed we noticed a tear in it. We are unsure if it broke during sex or as it was being removed. I’m also breastfeeding and still bleeding. How likely do you think it is to get pregnant I know your really fertile after pregnancy but we don’t think we’d be able to handle another pregnancy so soon. Anyone else been in this situation?? I’m panicking
