Aww hun, I am so sorry that you are feeling so down.
Believe me I know what your going through, my two bros & two elder & one younger sis have babies now. Its like 5 small babies are there still they are always asking me when we are going to have a baby. We didnt tell anyone that we are ttcing only my forum friends knows it. & we have been married also only 11 month(feb 16 2006) now, though we were together for 5 yrs.
Sorry for the long reply.
I know how much more you will be going through when it has been 7 yrs for you.
But dear still it will happen for us too, I do pray a lot for everyone ttcing.
Lots & lots of baby dust to you hun, hope ovulex works for you & that next month you get a bfp.
Good luck
