gangle - you asked why I left it til mid-thirties to start ttc, partly it was because I did not get married until I was 33, and did not want to start ttc til we had had at least a year of married life without children. I did not want to leave it any later as I was concerned about how long it might take to concieve being that bit older. As it happens both my children were concieved on the 4 month/cycle of trying.
Then there was also the issue of jobs, it had to be at a time that I felt that I could take a career break. It is difficult leaving a great job, and it is difficult to find satifying part-time work that fits in around children. But having said that, last summer I took 4 months off to be a stay-at-home-mum, and loved every minute of it. I am back working full-time at the moment and miss my children"!! I hope to go back to part-time very soon, so that I can have the best of both worlds. It is a thing to think about before having children.
As for feeling unattractive during and after pg, I have to say it was not all that bad, I did have a few moments of sadness when stretch marks appeared over the underside of my belly, but my darling dh said "they are the firey marks showing the great result of our passion" and despite it being corney, it really helped me re-evalutate my view of myself, and think more positively.
My relationship with my hubbie changed, but is just different, not worse or necessarily better, but still good. We do find it difficult to not talk about our children when we go out for a night, but that is ok too.
Becoming a mother is a miraculous life-changing experience, but I would not discourage anyone from doing it as it is also the most precious of experiences too.
I hope you are finding this helpful in making your decision as to whether now is the right time for you.
