Due to individual differences, the time of consumption may vary. Usage during pregnancy: 3-5 grams each time, once every other day, in small amounts, this method can be consumed for about 40-60 days. There are many claims that bird’s nest is more effective when consumed in the first 3 months of pregnancy and the second 3 months of pregnancy. In the first 3 months of pregnancy, the placenta is not yet developed and other external factors can easily lead to miscarriage. If you have a history of habitual miscarriage, you can take bird’s nest after pregnancy and stick to it until the first 3 months of pregnancy. During the second trimester, pregnant women who have a history of birth control can also consume bird’s nest. If you experience any uncomfortable symptoms during consumption, you should stop immediately and seek medical consultation if necessary.
