Lavatea, our dd was a very faint line 13 dpo. I think the problem here is not a faint line, it is the fact that you kept testing, IYKWIM. Most people would stop at that point, so there is not so much talk about what happens or does not happen to faint lines.
I am having the first cycle for a looong time where I have no signs of ovulation approaching by cd 16. Well, I had them right after af, but doubt I actually ovulated. I am blaming this on too much progesterone last cycle. Yet, I am only using cream, so I am not sure it should be able to cause this. (It is so often mentioned how the creams are so weak...) Whatever. I am actually kind of enjoying this limbo. I am tired of ttc and looking for what to do, what is the "plan" in my life (not mine) when it comes to kids.
Dd (soon 6) and I were in a store yesterday. All of a sudden she started crying and said she she has been praying for 3 years (true) and there is still no baby. She said it hurts her to see all the little outfits and that she no longer likes seeing a friend's baby. (I had wondered what had happened, because she liked loving on that baby not so long ago, and did not want to have much to do with her last time.) This was sad and interesting, as I have been calmer about things, lately. I do know that it is hard on dd that her younger friends keep getting more siblings. (One pregnancy we found out about just last week.) It was hard to know what to say... Dh and I can be thankful that we at least have dd. She, however, cannot not, you know. We at least have one child, but she has 0 siblings. Interestingly, I think in her own way dd goes through the same things I do: She loves babies and would love to have one to cuddle. She cannot understand why others are given so many kids, even if they don't look after tham very well. I have always known she was hoping for a baby, but had not realized how many emotions she has about it.
