i just want to clarify your case KABAYAN, youve mentioned that your visa was already transferred to the company, but you also mentioned that you did not undergo your medical yet, as far as i know, medical processing is part of the RP visa / nor working visa...den you should say that you already had your medical before.
In your case, you need to be sure first if you really pregnant, if so, then you need to talk to your company if its okie with them, bec. if not, den they can cancel your visa or employment with them.
