nipple pain

Vanessa • Wifey to my loving husband 💍
for the past week I have been feeling this weird sometimes sharp pain in my left nipple. I am on birth control and get my period tomorrow but never had this pain ever before. I know I'm not pregnant and my nipple doesn't physically feel hot but to me it feels hot.. if that makes sense. if I bent down my nipple shoots a pain if I move the wrong way it shoots the pain but it's only the left nipple/ around my nipple. I'm very nervous buy don't want to see a doctor if it's not serious because I'm only 20yrs old and breast cancer is very very very low for this age.. anyone feel this pain sometimes? am I freaking out for nothing ?
