When to start TTC

[DandelionBlue]

Thought I'd get some input from the ladies on this forum.
We are trying to figure out when to start our TTC journey.
I'm currently 28 and he is 32.
We are getting married at the start of October and going on a minimoon in the UK straight after. Then thinking of having a proper honeymoon in Japan in April. That's when we originally decided was the best time to start. Which if we fell pregnant immediately would mean due date would be in December. Which would be perfect.
I am locked into my job until November 2019, because they paid for my studies. If I left any earlier I would need to pay them back 3000£. But we are hoping to move away from London and buy a house in Yorkshire straight after. The idea is to downsize so that we can live off his wage for a while.
But I am now reconsidering our timeline. I realise it can take a while to get pregnant. Si maybe we dhould start earlier? Ideally I would like to time things so that I am on maternity leave when we move to Yorkshire. I don't want to start a new job and then leave on maternity leave straight after. And I also don't want to wait any longer because at 28, I can hear the clock ticking. I always imagine I would have my first around this age.
I am also trying to lose weight to reach a healthy BMI. And that will realistically take me at least 5 months.
Any advice? When would you start?

@DandelionBlue knowing what I know now I personally wouldn't wait as it took 18 months to conceive DS when I was 25 and currently taking 3x as long ttc#2. But I have PCOS. DH now getting checked out too so we may have underlying issues. But my SIL gets preg as soon as she stops the pill and one time she had still been on it!! So everyone is different. It's up to you what risk you want to take...risk getting preg immediately and have to pay back that money or glad you started now because it possibly may take you a while! Good luck making the decision.

If it was family asking me I'd tell them to go for it now coz they'd never regret it! You always work something out!

My OH and I are having a similar conversation and think we have decided to just go for it and if we are extremely luckily that it happens quickly then we can just deal with it. I am 32 and he is 34 and for the past couple of years we always seem to be waiting for some reason or another but we have got to a point where if we don’t go for it we might run out of time.

Only you can decide though. Congratulations on your upcoming marriage and good luck whatever you decide
