NVP Symptoms and Effects
I am pregnant and in my fourth month. I have not had any vomiting until the 13th week of pregnancy. I did have nausea, with light gagging reflex a few times during the first trimester, but not vomiting. Why is this starting in my second trimester??? I have tried taking vitamins at different times, not eating certain foods, eating certain foods. In all my research, I can't find anything that reports on vomiting in the fourth month. With my first child I had no morning sickness at all. I was 34 years old. I am now 38 and will be 39 in two weeks. Is there something wrong? I want to educate myself before I go in for my Dr visit. Please help me.
NVP affects between 50 and 80 percent of all pregnant women, mostly in their first trimester. The fact that you had some nausea and retching only sporadically before your 13th week might indicate that you could be affected by NVP in the second pregnancy, although with an irregular pattern. You do not indicate whether your vomiting now is accompanied by constant or intermittent nausea. You should go to your doctor who will be able at this stage of your pregnancy to check and eliminate other causes of vomiting such as high blood pressure or urinary infection. Should NVP be confirmed, treatment is available through your doctor. You can also call our NVP Helpline at 1-800-436-8477 for more information.
