Baby fever 5mpp, breastfeeding!

I want another baby, my babe is 5 months tomorrow, I’m still breastfeeding, and he’s an Ivf baby! I’m feeling a little down, I love my little guy, and I’m so overjoyed that I am so lucky to have him, but I can’t help but think about never being able to get pregnant naturally! I had an hsg test done 3 times which I supposedly have blocked tubes, with no explanation. The doctor did it 3 times with a different answer each time, first my left was blocked and my right wasn’t, then my right was and my left wasn’t, and then both of them were! 😒 I can’t help but wonder if they really are blocked, and maybe it was just my pcos causing my infertility..
