We would like to inform you that There is no legal provision that prevents the worker from being pregnant, provided that this pregnancy is lawful and legal. We also recommend that you wait until the first six months have passed because the UAE Labor Law grants the employer the right to terminate the employment contract during the first six months without warning or reward and without the need to provide any reason to terminate the contract of employment.
Here is the text of the UAE Labor Law, concerning your inquiry:
Article (37):
The worker may be appointed under probation for a period not exceeding six months and the employer may dispense with the services of the worker during this period without warning and without end of service reward. The worker may not be appointed. Under experience more than once with one employer, and if the worker successfully passed the period of the experiment and continued to work, the period of service shall be calculated.

If you have another question, feel free to ask us and we will answer with pleasure.
