Pregnancy reactions in the first month and a half of pregnancy are usually very obvious, mainly manifested as nausea, vomiting, dizziness, weakness, drowsiness, not thinking about eating and drinking, preferring idiopathic food, some people are afraid of cold or heat, and some people appear to have a lot of saliva, which are all common symptoms of pregnancy reactions. However, the early and late appearance and severity of symptoms differ for each person, so if these symptoms appear in the first month and a half of pregnancy, they can be temporarily observed without treatment if they can eat normally. Patients should take rest and relax, and the symptoms will usually reduce or disappear in about a month. Some people do not have any reaction, i.e. they do not feel anything after pregnancy and are able to eat and drink normally. As long as the fetus develops normally when the ultrasound is done, there is no need to worry.
