What is the chance…

[NKD]

40 year old
Withdrawal method/Condom used (towards the end)
Only dtd once this month.

Slightly panicking at period being late.

I wouldn't worry too much. My partner and me used withdrawal for years and concieved first month not doing it.

I should maybe add I had a miscarriage 2 months ago so have been careful since then as DH has made it very clear he wants no more children and would have no involvement should another one arrive.
(He is on waiting list for vasectomy).

I’m hoping stress is just playing with my hormones (and my age) 😬

Maybe not my place to say but your DH said he'd have no involvement? That's not on! I hope you are OK and get the outcome you want, either way. ❤️

No you are absolutely right - he dealt with it throughly shit last time - so I’m not even telling him.
He has his reasons (we have older kids already) and he doesn’t want to go back to newborns at his age.

saying not wanting to go back to newborns and older kids etc is absolutely understandable, what isnt is saying that he would take nothing to do with it. if he is old enough to have sex then he can pay the consequences of that as it is just as much his responsibility.

You're probably ok. 41 here, have been TTC for 18 months, must have DTD around 60 times in fertile periods over this timeframe. Still not preggers. But obviously it's a possibility, so test if AF is still AWOL in a day or 2 (if you're sure of dates).

If your period is already late then you should get an accurate result on a pregnancy test. I’d take one to put your mind at rest so you can stop panicking (or at least know for certain).
It’s unlikely but not impossible.

If you’re not pregnant and you don’t want to get pregnant is it worth speaking to your GP or a sexual health clinic to discuss other forms of contraception until your DP can have his vasectomy? If you’re both very clear that you don’t want more children then withdrawal probably isn’t a reliable enough form of contraception for you.
