孕已知觉，用布一幅，阔六七寸长，可横缠腰间两道者，常束腰间直至临盆方解。盖胎当未长成得此腰膂
有力，偶或扑跌不致损胎。及临产解开，腹中乍宽，胎儿转身亦
易，诚护胎之妙诀也。
妇人初受胎，一点精血凝成一粒，形如珠露，乃太极动而生阳，天一生水谓之胚。此月未有宫罗，在KT 户
之间未入腹内，若无寒热疼痛，不必服药。尤不可触犯房劳，致成暗产。
妊娠受胎一月满足，精血近阳，珠露变成赤色，形如桃花瓣子，乃太极静而生阴，地二生火，谓之 。
此月在母阴户内六七寸，已入腹内。未入衣里，或动或不动犹有狐疑。若吐逆、吞酸，有孕明矣。或偏嗜一物，
则知一脏之虚。如爱酸物，乃肝脏不能养血而虚也。
三月形如蚕茧，渐渐长大。一头大一头小，其微圆，未入宫罗，已至脐下，微有薄衣包裹。乃太极干道成
男，坤道成女也，故谓之胎。此月胎最易动，最宜防护。
四月男女已分，始受水精以成血脉，形体初具，六腑顺成。此月已入宫罗之室，衣裹渐至丹田之所，忌食
牛马、猪头诸般发毒之物。
五月始受水精，以成其气，筋骨四肢初成，毛发始生。此月已入宫室，其胎安稳。令人摸之，如覆杯者是
男，如肘颈参差起者是女也。
六月始受金精，以成其筋，口目皆成。此月男动左，女动右，常在脐中，渐渐浮上，如鱼浮水一般。
After pregnancy is confirmed and fetal movement is perceived, use a piece of cloth, six to seven inches wide and long enough to wrap horizontally around the waist twice. Bind it tightly around the waist until delivery, then remove it. This provides support to the lower back and lumbar region (腰膂) while the fetus is not yet fully developed, preventing injury from accidental falls. Upon labor onset, removing the binding allows the abdomen to relax, facilitating fetal turning. This is indeed a wonderful secret for protecting the fetus.
When a woman first conceives, a particle of essence and blood condenses into a grain, shaped like a dewdrop. This represents Taiji moving to generate Yang; "Heaven generates one as Water," termed Pei (Embryo). At this month, it has not yet entered the uterus (Gongluo), remaining between the vaginal opening and the abdominal cavity. If there are no symptoms of cold, heat, or pain, medication is unnecessary. Crucially, sexual activity must be avoided to prevent missed abortion (Anchan).
At one month of gestation, essence and blood approach Yang; the dewdrop turns red, resembling peach blossom petals. This represents Taiji stillness generating Yin; "Earth generates two as Fire," termed Tai (Fetus). It resides six to seven cun inside the vagina, having entered the abdominal cavity but not yet the uterine interior. Fetal movement may be intermittent, causing uncertainty. Vomiting and acid regurgitation clearly indicate pregnancy. Cravings for specific foods indicate deficiency in corresponding Zang organs. For instance, craving sour foods indicates Liver deficiency due to inability to nourish blood.
By the third month, the fetus resembles a silkworm cocoon, growing gradually. It is larger at one end and smaller at the other, slightly round, not yet in the uterus but reaching below the umbilicus, wrapped in a thin membrane. This corresponds to Qian Dao forming male and Kun Dao forming female, thus called Tai. The fetus moves most easily at this stage, requiring utmost protection.
By the fourth month, sex is distinguished. It begins receiving Jing of Water to form blood vessels; the body shape is initially complete, and the Six Fu Organs are smoothly formed. It has entered the uterine chamber, with the wrapping extending towards the Dantian area. Foods such as beef, horse, pork head, and other "fa du" (toxicity-inducing) substances should be avoided.
By the fifth month, it receives Jing of Water to form Qi; bones, sinews, limbs, and hair begin to develop. The fetus is stable within the uterus. Palpation reveals: if the shape resembles an inverted cup, it is a male; if irregular protrusions resembling elbows or necks appear, it is a female.
By the sixth month, it receives Jing of Metal to form sinews; mouth and eyes are formed. Male fetuses move on the left, females on the right. The fetus remains near the umbilicus, gradually rising, resembling a fish floating on water.
