I just wanted to say hi and welcome you. I am so very sorry for the loss of your son Tyler. My heart breaks everytime we meet someone new who has lost their precious angel.
My husband and I lost our first son in July of 2003, he was born at 26 weeks and was with us for five days. I knew immediately that I wanted to try again, as soon as my doctors would let me. Thank goodness my doctors made me wait because looking back I know I wasn't ready but that desire was just so strong. When we actually started TTC again I was terrified - a bit excited as well but so scared of what might happen.
As far as when is the right time - I really think that's something that you have to decide with your husband and doctors. My OB wanted me to wait at least six months, my peri liked to see closer to a year. At six months, I was chomping at the bit to become pregnant again. Because of some medication that I was on, we waited a few more months and became pregnant again 10 months later.
Have you been tested for any underlying disorders that can increase your risk of preeclampsia? One thing that I would really suggest is to meet with a peri for a preconception consult. They will likely test you for the disorders if it hasn't already been done, they will also be able to discuss your case in detail and provide you with a better picture of your specific risks. My husband and I met with three different peris before we found the one that we were comfortable with and that took us through our 2nd pregnancy. I truly believe that the highest level of medical care can make a significant difference.
Please take care and let us know how we can help. I saw that you've already posted a response to a member's post on the TTC Board, it would be a great place for this subject as well - you'll find many women going through the same thing with you.
Again, I am so sorry for your loss.
