Q: Is it normal to have breast tenderness 10 days after ovulation?
A: It is normal to have breast tenderness after ovulation. This is usually due to progesterone, a hormone produced by the ovary after ovulation. Breast tenderness is among the typical pregnancy symptoms, but usually breast tenderness in pregnancy appears only after you miss your period and there is a positive pregnancy test. At that time it is related to the rise of the pregnancy hormone hCG which typically does not rise to significant levels until 3-4 weeks after ovulation, or 1-2 weeks after you miss your period. If you experience breast tenderness within 1-2 weeks after ovulation and before you miss your period, it's unlikely to be a typical pregnancy symptom. That does not mean you are not pregnant, but your breast tenderness this early is unlikely to be related to your pregnancy.
