Maternityaction.org.uk is usually pretty good and easy to understand for maternity leave rights questions. I don't know what exactly you're after but generally speaking, if you're on probation I'm pretty sure you're still legally entitled to mat leave but it's unlikely you have worked there long enough to get Statutory maternity pay (SMP) but you will probably still qualify for Maternity Allowance (MA). But have a look on the website, it'll likely have an answer to whatever your actual question is. (I'm assuming you're from the UK)

What's the issue? Were you with the company before you got pregnant? If so you'll most likely qualify for SMP. If not you'd get maternity allowance which is almost the same except missing the 90% salary for the first 6 weeks and just paying the £180ish a week instead.

If they offer enhanced maternity pay it'll be entirely at their own discretion and that varies wildly between companies. So you'd need to check the policy and eligibility criteria.

yeah I started at the job before I got pregnant but now there extending my probation til October to review my performance but I know it won’t be good because I’m going to be heavily pregnant so feel like there just going to sack me to not pay me if

Definitely look into it but even if they did they may still have to pay you SMP. They claim most of that back from the government anyway so it doesn't cost them much.

While being pregnant is a protected characteristic they can still fire you for other reasons, especially if there are performance issues like you mentioned. I'd try not to worry too much! Xx
