Is it possible to have sore and swollen breasts only days after conception?

While it's possible to experience breast tenderness during the early days of pregnancy, it's unlikely for these symptoms to occur a few days after conception. The earliest detectable pregnancy symptoms usually start 6 to 10 days after ovulation, which typically happens around day 14 of a 28-day menstrual cycle. However, it's more common for pregnancy-related breast changes to become noticeable a few weeks after conception.

Breast tenderness is a common early symptom of pregnancy, but it's not always a reliable sign, as it can be caused by other factors, such as hormonal changes during the menstrual cycle or certain medications. If you're experiencing breast soreness and swelling, it's best to take a pregnancy test or consult a healthcare professional to confirm or rule out pregnancy, especially if you've had unprotected intercourse.
