The problem is that there are many women who are also having trouble conceiving who are hurting just like you and who need support too. I am just giving you the other side of the story, because there are many women who feel they have no where to turn. They don't feel at home in the regular TTC threads but can't get support here. I don't think people realize how hurtful it is when people dismiss your pain so I felt that it is important to bring this to the board's attention.
I may be wrong, but I think one possible reason the mods have not defined LTTTC is because everyone's definition of it is different. There are also different levels of "trying". I've seen women who've been TTC for two years and still don't know what an OPK is. On the other hand, there are other women who have already completed a fertility workup and been through several IUIs by the time a year is up. I don't think you can automatically say that the woman trying for 2 years necessarily needs the support more than the woman who hasn't been trying as long but has been more proactive. Some women get to the point of despair faster than others so it's just not fair to put an arbitrary limit on it. Also, what about the women who have had fertility problems in the past and are now trying for #2 and knows from the get go that the journey is not going to be easy.
I understand the need for a safe haven, but I don't think it is realistic to shield certain LTTTCers from every single thread or post that might cause pain when the poster has a legitimate reason for posting. There are other areas of the board with more specific criteria, and areas where you can create your own groups that can be more of a safe haven.
