pregnency in China - הריון ולידה

,hi
i just found out that i am pregnent- in this weekend its going to be the begining of the 5th' week.
we just arrived China on sunday and planed a one month trip in China.
beside the flight to israel, we already had one flight and going to have another one in about week or two.
at the moment i am feeling good, but i am little scared to make any harm.
what should we do? if you think its reasonable to stay- is there any suggestions?
i have with me PRENATAL B12 and SIDAN.

thanks for the advice :)
