I am 28 wks pregnant, and I was stung by a wasp about 13-14 hours ago, and just threw up about 45 min to an hour go. I was wanting to make sure that I was ok. After vomiting my stomach felt better, and I now feel fine. I haven t had any other reaction to the sting other than the typical slight redness with a little swelling and soreness around sting site. As far as I know, I am not allergic either. Please advise if the sting may of cause the vomiting or if just possibly something I ate made me sick.
