id say if you and your fiance are ready go for it, it sounds like this it what both of you want soo i wish you the best of luck and lots of baby dust :) im not sure about the fertilaid, but since your confident id say again GO FOR IT :)
I personally don't believe that age should be a decision maker if you have a baby or not. If you and your fiance are ready, and you are able to provide for this child and able to take on all the responsibilities that are necessary to care for a child then I say go ahead. Do what makes you happy, don't worry about what everyone else has to say. A lot of people say things, not meaning to be mean, but I'm sure they care about you and only want the best for you. You know if you are ready or not, but just be aware that having a child is a life long responsibility and it takes a lot of hard work and patience. Good luck and do you!
