I think as long as you are physically, mentally, and financaly ready then go ahead. You are young but I think from hearing you talk about your baby and everything that had gone on I do think that as long as you as a person can handle it, then go for it.
I was told not to try to have any more babies after what happened with my first baby. I know you are a lot younger than I and our situations were very different. I am 24 years old and was 22 when my first baby passed away, and at that time I was told by many doctors not to try to have babies because I myself was really close to dying. But I am pregnant now at 27 weeks (yay for 3rd trimester) and I have had a perfect pregnancy (other than the morning sickness). I couldn't ask for a better pregnancy. And this time I have shown no signs of getting sick, and my baby couldn't be more healthy. Everything is totally opposite from my first pregnancy. (i was sick and so was my baby.)
there is a right time for everything, and if you believe that this is the time. And no one could tell you what to do in this case just make sure you are healed in all aspects of the word.
