Thats a good question.
As i am aware...
A company whom is buying another company has to offer all the workers equal rights to the jobs thats available.
Everyone has to re apply for that job, so everyone is in an equal position.
If you are not selected you can still take it to tribunal for unfair dismissal.
There are regulations that govern what happens to employees when someone new takes over a business.

Existing employees of your new business
These apply to all employees when a business is transferred as a going concern, meaning employees automatically start working for the new owner under the same terms and conditions. Workers are protected under the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE), when all or part of a business is bought or sold, the terms and conditions of the employees who transfer in the sale are preserved. In other words, in almost all the cases the new employer cannot change the transferred employees' terms and conditions to match those of its existing employees.
Employment tribunal awards
When you buy an existing business, you might decide you need to employ fewer staff. But be careful about making any changes, as an employee might take a case to an employment tribunal for unfair dismissal or unfair selection for redundancy. It's best to consult a solicitor before making any such changes.
Inform and consult employees
If you do want to discuss reducing employee numbers or reorganising staff, it's a good idea to do this once you've completed the due diligence period, but before you take over the business. As the new employer you should inform and consult all employees - including employee representatives - who may be affected
Being Pregnant - You are far more protected in the workplace legally due to this.
Obviously if they do not choose you, you can take the matter further and question there decisions and obviously link it and ask was there decision based on the fact you are prgnant? do they see this as a disability? do they see this is a way of you not doing your job?
i believe if your made redundant you wont be entitled to your work maternity pay, but you should still be elligable for the government maternity.
Good luck!
