Can I be pregnant?

I’m 9 weeks pp c section , I started having sex at 6 weeks . We didn’t use any protection but he wasn’t coming inside me either . I haven’t even gotten my first postpartum period! I will be going to the clinic next week when I have the money to get the iud . I’ve been having discharge but that’s it and I’m breastfeeding/bottle so idk if that makes any difference I already stopped having sex.
