TMI!!! NO COMMENT ON MY BOOBS?? Update!

This is seriously a crisis for me!!! My boobs are getting red stretch marks!! I haven't gotten any advice yet, but I'm seriously having an issue with this... My boobs never grow as a PMS so why are they growing now??? Can anything else cause this besides pregnancy?? I haven't tested yet, but I just want to know just in case I test and BFN is there anything else that would cause this... Pics below.. Trust me it looks worse in person, like a cat scratched me..

Update: Hello everyone thanks so much for your help in trying to figure out why these stretch marks appeared, turns out IM PREGNANT!!! After over a year of TTC from two miscarriages, I finally got another chance! I'm so excited I'm crying! I thought this would never happen again and I feel like I owe it all to Premama fertility. It's the only difference I've made and it worked!! Please pray for me that I have a happy and healthy 9 months!!
