As we said above, this is very relative and depends on the type of relationship you want to establish. However, it is important that a pregnant candidate be prepared to engage in this process and be aware of the benefits but also the risks and possible problems that may arise.
It is important to have professionals who help and guide all the parties involved from an individualised point of view. Having the support of lawyers, agencies, psychologists, etc., is fundamental in order to minimize short and long term problems as much as possible.
On the other hand, it is highly recommended that the surrogate pregnant woman and the future parents be in contact during the pregnancy and support each other. In short, attending to the needs of each one is fundamental for everything to go well.
