NVP Symptoms and Effects
my daughter is 4 mths. pregnant with twins. She just started having alot of nausea. Could you tell me if this type of pregnancy can cause this more than the normal pregnancy? Thank You
Twin pregnancies may cause added NVP, although this is not true for everyone. You also mention that your daughter is 16 weeks pregnant and has just started having a lot of nausea, but you don't indicate whether she experienced any NVP previously during this pregnancy.
Typically, nausea and vomiting due to pregnancy starts in the first trimester and is over by 16 weeks (for most women). If your daughter only started now, her symptoms should be monitored and discussed with her doctor. If she has had symptoms all along and needs more information, please ask your daughter to call our NVP Helpline at 1-800-436-8477.
