New here new lump

Hello all,

ive just been told I need to go to the two week wake breast clinic. I'm 33 years old, mother of a two year old. I found an oval shaped lump in my left breast two days ago. It's not small but not large. It's not painful to touch but I have some discomfort in the entire left breast every so often throughout the day. No history of genetic breast cancer in my family. I take vitamin D and CDB daily and eat healthily. I'm scared and confused as to what this is and why it's sprouted up. 
fingers crossed it's a fibroangioma. I had uterine fibroids before my pregnancy and wondering if there's a connection. 
 

In the mean time, trying not to freak out here! Just venting I guess.

thanks for reading and feel free to leave a comment :)
