Hey thanks for your faith in the health care Magic I have gone through your question and I understood your problem. A wasp sting that occurs while a woman is pregnant is of no serious concern unless she has an allergy. The pregnancy is not at risk because of a sting. The sting should be treated at home as normal but if there is a concern it is best to seek medical advise from the doctor. But still I will suggest as every pregnancy is precious you should visit an obstetrician. Thank you.
