I am a 25 year old female, i was late to develop, started my periods at 15, got pubic hair at 18 and my nipples had always been relatively small. I have one breast noticably larger than the other.
For about a month now i have noticed my nipples have changed in size, getting slightly bigger and darker, sometimes throughout the day i can feel them tingling. What is this? Please could someone help. Thankyou.
