Disappointed and not pregnant.

So this is sort of a long post, sorry in advance.

I really don't know whats wrong with me. I'm really missing being pregnant, I have a 4 month old daughter - and being her mummy, being able to cuddle her, kiss her, play with her , everything surrounding her, all of that means the world to me; I'm beyond lucky and love her more than anything.

But nothing seems to shake this feeling of wanting another baby, wanting to be pregnant again. Every time my period arrives, I'm always slightly disappointed that I dont have another little baby flourishing away inside of me, disappointed that I'm not carring another baby. Is that wrong?

I mean I'm not to sure, maybe its because I have this ever growing fear that I'm never going to have any more children, maybe it's because I'm worried that my endometriosis is going to get worse, or in fact all of the problems I have fertility wise are going to become worse...

I just don't know, I love my life, my daughter is the best thing that has ever happened to me.

I just wish I could have another. Any other mummy in the same boat?
