Until now, most people think that pregnant women are particularly picky about what they eat. For example, many pregnant women don't like greasy food, and they will vomit when they eat greasy food. There are also women who will change their previous eating habits after pregnancy. They used to like eating, but now they don't eat. They didn't like eating before, but now they are eating hard. Some women eat very little during pregnancy. So the ancients believed that when a woman's eating habits changed greatly, she became pregnant. In fact, the reliability of this method is not very high, because when a person's gastrointestinal diseases occur, his eating habits will also change greatly. So this method is not accurate.

Some people think that pregnant women who drink honey before going to bed will have swelling pain or diarrhea. If she drinks honey water without this phenomenon, it means that she is not pregnant. This practice is not accurate at all, because as we all know, if people have a bad stomach, drinking honey water will cause diarrhea, which is even more unreliable than observing women's eating habits.

Sometimes, if a woman is suspected of being pregnant, she will use her excrement to water the wheat. If the wheat germinates, it is considered pregnant. Later, scientific research proved that this method has 70% accuracy. Because the hormones in women change during pregnancy, the germination rate of wheat will increase.

However, these methods are not 100% accurate, after all, ancient medical technology is not in place.
