Hi, I'm Sommer, a stay at home mom of 3 awesome kids.. we are really hoping for 1 more. AF just started 3 days ago.. putting an end to cycle number 7

I am 30, will be 31 in Oct, and have decided that we will not continue to try after next spring. We entered our marriage with a child in tow (mine), and dream of a day when we will have time to ourselves.. like that will ever happen

, so we feel the kids need to be pretty much raised by the time we are 50, so we can still enjoy life a bit and our future grandchildren too! Honestly my mother was an older mother (her last was at 40) and I have seen the toll it has taken on both my mother and my sister, and do not wish that onto anyone.
Anyway.. My kids are 8 (4 1/2 ttc), 2 1/2 (just over a year ttc, but used no b/c ever), and 1 1/2 (surprise!). At the advise of my dr I waited a year after #3 to let my gaurd down. He turned 1 Dec. 29th and we started trying with my cycle that started 1/1/07. I have learned so much... and feel we have to be doing everything right. We BD at least every other day until just after O, and then I try to avoid it after for fear the other O will prevent an egg from sticking.. pretty silly huh? I usually O around CD 17, but have anywhere from CD 14 to 22, and have a usual LP of 11 days.. not too short, but not long either. I am a faithful charter, I have my alarm set for 4am everyday because most times DH has to get up for work then.. so even on Sunday I wake up at 4 and give my thermometer a kiss.
I am beginning to feel #4 will never happen and I should be happy with what I have, after all many couples don't even have 1. I am happy.. but I'm not content. I have an overwhelming feeling that our family is not yet complete.. and although I long for another girl.. I feel another boy is what is missing. (We have 2 boys and 1 girl, the girl is in the middle).
I know this is getting long, so I will end it in a second.. I will just say I am happy to have found this board.. and hope to get to know all of you.. if there is anything I have missed or anything you would like to know about me, please feel free to ask.. I am a pretty easy going person, and love questions (none are dumb and most don't annoy me.. they can't I homeschool

).
