Pregnant after 4 months postpartum!!

So.. I’ve been feeling really nauseous and my feet would get super and swollen and they would hurt. So, I thought to myself. When is my period due?? I’m a week late. I took 3 tests and had faint lines until today, it was almost as dark as the control line. I’m super frustrated because how can I be so irresponsible? It took me a while to conceive my son and just the one time that I was being dumb, I actually end up pregnant! I breastfeed also so I thought it would’ve been harder also, I was wrong. I don’t know what to do or think! 🥺 is course I’m going to keep my baby but it’s just so quick!
