Job offer in tww

[Frizzy1986]

So I think I'm about 8dpo on day 22 of what is usually a 27-28 day cycle.
I had a slight pink tinge in cm on 3dpo (way too early to be anything I guess) and have been having mild cramps since. I usually wouldnt get cramps until 3-4 days before af.
We are on month 7 and obviously I'd like to be pg, but we just have to keep going and I'm trying my best to remain calm.
My issue is that I've just been offered a job. I don't want to accept if I'm pg as I'd lose maternity benefits, but I don't know how long I can keep them waiting before giving an answer.
If I am pg then I'd be honest and tell them and they can decide if they still want me and my terms etc. What will be will be and all.
In my head, I'm totally not pg as although I've been cramping more than usual, the cramps are starting to get a bit stronger at times and I know your body can have a mind of its own month on month.
It's just my hopefulness that's screwing with my head, and it's stressing me out.

How long would you have to work there to get maternity benefits? If it something like 6 months and even if you aren't pregnant this cycle, you intend to keep trying etc. Then it makes sense to stay in your current post to ensure you get pregnancy benefits.

It's only the smp that bothers me and that's 26 weeks employment by week 25 of your pregnancy.
If I accepted, we'd stop trying but don't really want to if I am pg as we can't afford to not get those first 6 weeks of pay.
Feels bloody typical as I could very well not be and then have missed the opportunity.
