After my pregnancy with my babies it took me around 8 weeks which is 2 months before I started to really recover at least somewhat from the pregnancy.
However it took me 6 months to really fully recover from pregnancy and I didn't want to try for another baby until a year later.
You can try sooner than a year to have another baby but for me I could not get the strength to even try again and was too exhausted after the pregnancy and taking care of the baby to even bother with trying for another baby.
When I first had my first baby I said that I would never want to go through that pain again to have another baby and said I was satisfied with the one baby I had.
But a year later I decided that I loved that baby so much that I was willing to go through the pregnancy again and having to recover again.
You might think that you wished you never got pregnant and went through the pain misery of pregnancy but after being with your first baby for a year at least then you'll likely want to have a baby again.
