Hello all, can I join please?
I've been very conflicted for the last year about whether to TTC #3 (I have an epic thread on Larger Families, if anyone is interested).
We have 2dds aged almost 6yo, and one who who is 2.9yo. Both took a while to conceive, with dd2's conception being particularly stressful: 2y - and she was conceived on my 6th cycle of Clomid.
Essentially, I've been undecided because I'm worried about rocking our little boat; we'll need to move house and I worry about how another sib will affect them. Also, my two beauties can be a handful sometimes ... how to balance 3?
Also, if we had another baby, that baby would be born by ELCS (VB dd1, ELCS dd2). I recovered well after dd2's birth but worry that I won't be so lucky with another (in terms of the actual surgery, recovery and postpartum effect upon my body).
Then there's the actual getting pg bit! 
But, dh has explicitly said that he would like one more baby and this has influenced me a lot. I think about whether or not to try again on a daily basis and I think I may regret not at least trying further down the line.
At least if we try and don't succeed, I'll know we tried. And I'm already so fortunate to have the two gorgeous girls we do have so ...
We weren't careful with contraception this month. I don't think we did it on the right days, so unlikely to be pg. AF is due 6th Feb, so we may well take the plunge in Feb!
(I found TTC and it not happening for a long time incredibly distressing and isolating last time, as it was only me, DH and my DM who knew. It's going to be nice to share
).
