Chest swelling is not a precursor to pregnancy. There are more reasons for chest swelling, and it is not only after pregnancy, for example, women may also experience chest swelling during ovulation and before menstruation.
Chest swelling may be physiological or pathological. During ovulation, before menstruation, or after pregnancy, women are affected by increased hormone levels in the body, which stimulates breast ducts to proliferate and expand, resulting in a feeling of chest swelling. Pathologic considerations are cystic hyperplasia of the breast, breast cancer and other causes.
Simply by relying on the symptom of breast swelling, it is not possible to determine whether or not you are pregnant. The precursor to pregnancy is usually a woman’s menopause, which is suspected to be caused by pregnancy if the menstrual period is suspended after intercourse.
To determine whether you are pregnant, you can go to the hospital 10 days after intercourse to take a blood test for HCG, or you can use a pregnancy test 14 days after intercourse to determine if you are pregnant.
