Stick it out or just quit - WWYD?

[YukoandHiro]

Just that, really.
I have one DC (2) and am ttc a second. It took me ages to get pregnant with the first (including losses) and I'm now in my late thirties, so no guarantee a second will even happen.
I'm in a senior job in my industry. I returned PT (three days a week) a after having my first. It's been mostly OK, if stressful as I inevitably do far more than three days' work and only get paid for the three.
But I don't work well with my boss. Everyone else is great. My boss is a massive sexist and has made it clear he thinks I'm worse at my job now because I'm a mother. Nobody else thinks like this, and otherwise in the company my work is well thought of, but obviously he has massive influence. As a result I've begun to feel very undervalued and generally angry, and I've also outgrown my role (been in it five years) but it's been made clear there are no other options for me on flexi in the company as it's 55 hours a week or nothing in any role senior to mine now.
I'm tempted to just quit and try self-employment (i've done it before and it's possible in my industry - but it's hard to turn round a good income on it). But hubby thinks I should stick it out as we can't really afford for me not to get any maternity pay and I might be pregnant in a couple of months. But it's making me so miserable, I'm worried my DC is picking up on the vibes.
What would you do? Stick or twist?

I would stick it out for the mat pay and then either decide not to return or return for the minimum period to keep your full OMP. Then go self employed once things have settled.

Stick it out until you've saved enough to cover Mat leave.
Either you get pregnant soon and have Mat pay + some savings which would be nice, or you have enough to protect yourself and get to leave.

MAke a compromise with yourself/dh -give it 6 months in the hope that you’ll become
pregnant during that time. If not resign at 6 months. Knowing you potentially have a 6 month end point will make it more bearable as either way, the end is in sight

Stick for the mat pay.

Stick it out and focus on mentally disconnecting from the drama of your boss. Nod and smile. And I’d keep TTC and look for an alternative job too. Just keep all options open.

Like pp I would stay and keep saving until I had the equivalent of MAT pay. You could be pregnant by then in which case it would be worth staying AND having your savings.

I'm going against the grain here... there's nothing worse and more soul destroying than working in a job, with people you dislike. If you're that unhappy quit. I'm sat here at the moment with no job as I did exactly that (waiting for a contract for a new role tho).

But I would say, look for a job within a company that offers mat leave rather than starting your own. If you run your own business it's SMP, plus it's how you continue trading whilst you have a small baby. As you said it could be a good while until you are Pg, plus you've a further 8/9 months whilst pg of work. So you could be in the new job over a year before you go on mat leave.

Thanks everyone. I think that you're probably all right - it makes the most sense to just hang on in there, and the fact that I'm only PT does help.
I like the idea of setting a deadline. I now remember that I actually did that when I was getting frustrated with the stress levels at work before conceiving dd but in the end I did have a successful pregnancy before I reached the deadline. I'm going to discuss it with my dh this week.
Thank you! Good to read others' perspectives
