Periods come with plenty of symptoms – including stomach cramps, mood swings, headaches, a change in bowel habits – although everyone experiences differentthings. And one such change you might often notice during your menstruation is tender boobs.
Breasts can become sensitive during the time of the month, the same way they can in the early days of pregnancy.
But if you were wondering what the link between your boobs and your uterus was, wonder no more. Dr Lynae Brayboy, Chief Medical Officer at female health app Clue, has laid out exactly why this symptom can occur – and it’s interesting to see just how your period affects you in ways you never considered.
“The connection between breast tenderness and periods is directly linked to fluid retention,” explains the doctor. “The science behind this is that the hormone progesterone causes the smooth muscle around veins to relax. This can mean that fluid can’t drain properly from tissues like the breast.”
Progesterone is a hormone that is released in higher levels during the luteal phase of your cycle. That’s “the part of the menstrual cycle that occurs between ovulation and your next period, or the days on which your bleeding begins,” explains Dr Brayboy.
