Patient's question:
Hello Doctor! Is morning sickness a sign that the fetus in the womb is alive? On Monday (when I was 46 days pregnant), there was no fetal heartbeat or fetal pole detected during the ultrasound, but I have been vomiting and having poor appetite these past few days. Is there any problem with the fetus? Although the doctor said it's normal, I'm still very worried. I heard that some people didn't have a fetal heartbeat even after being pregnant for three months. I'm so scared. Please, Doctor, do I have a problem? Could you help me with an answer? Thank you!Doctor's answer:
Under normal circumstances, self-monitoring is not possible before the 15th week of pregnancy. For pregnant women between the 15th and 25th weeks, it is generally recommended to measure 2 to 3 times a day, with each monitoring session lasting about 1 minute. After the 28th week of pregnancy, as the fetus has relatively developed differentiation within the mother's body, the duration and frequency of monitoring can be appropriately extended. High-risk pregnant women with conditions such as hyperthyroidism or hypertension should be hospitalized promptly for fetal heart monitoring. Before the 24th week of pregnancy, the position for fetal heart monitoring is usually at the center of the abdomen below the navel or on both sides of the midline. As the fetus grows in the abdomen, the position of the fetal heartbeat also changes. After the 24th week, the fetal heartbeat moves to the back of the fetus. Under normal circumstances, the fetal heartbeat of a head-down position can be monitored below the navel, while the fetal heartbeat of a breech position can be monitored at the navel.
