If a woman becomes pregnant again while breastfeeding, the symptoms are exactly the same as those of non-breastfeeding pregnancy, such as persistent breast fullness, drowsiness, fatigue, dizziness, and even nausea and vomiting. After pregnancy during breastfeeding, the estrogen and progesterone in women’s bodies will continue to be high, so the high level of estrogen and progesterone will stimulate the development of breast glands and alveoli, resulting in obvious breast swelling and pain, as well as erection of nipples and local color deepening of nipples and areolas. Due to the influence of hormones in the body, women may also experience significant drowsiness, weakness and even dizziness in the early stages of pregnancy. At this time, the gastrointestinal tract is moving faster, so there is also a noticeable increase in appetite and hunger, but with the prolongation of menopause, it may cause constipation due to the slowing down of gastrointestinal tract movement, and may even cause nausea and vomiting as early pregnancy reaction. At the same time, because of the high level of progesterone, the basal body temperature often rises significantly, causing a woman to have a generalized low fever, but at this time there is no fever or other abnormal phenomena. Since each person’s constitution is different, the specific symptoms after pregnancy will vary from person to person, and not every woman will experience the above-mentioned symptoms.
