getting pregnant shortly after having a baby?

Has anyone here had or have babies close in age? I have a 6mo boy and baby fever is back and in full force 🙈 What's it like? Was pregnancy easier/harder? If you could have waited a little bit longer to have another instead of right away, would you? 
Side note I am still breastfeeding so would love to know if anyone has also gotten pregnant while still BF (he still nurses quite often so I'm not even sure what my chances are to get pregnant right now if I tried)
