Some people experience breast swelling after ovulation, which is related to changes in estrogen and progesterone levels in a woman’s body, but the presence of breast swelling does not mean that a woman is not pregnant. The earliest and most accurate test is to monitor the human chorionic gonadotropin in the blood, which can be detected from the mother’s blood one day after the fertilized egg is laid. There is also a simpler way to perform a urine pregnancy test, which can be done by purchasing test strips at the pharmacy. After pregnancy is confirmed, the patient needs to check the size of the gynecological ultrasound around 40 days after menopause to rule out the presence of ectopic pregnancy. If your period is delayed and you have a swollen chest, don’t take it lightly and don’t assume that you are not pregnant, but only after testing will you know if you need further treatment.
