I also use two Large Cups for both of my breasts and I have a smaller frame than you do. It was so frustrating moving from medium to large but keep doing what you are doing! It took me two week ishsss to fit in both of them and A LOT OF OIL TO KEEP THEM BABIES ON! lol.
No matter the amount of oil or lotion I use, my breasts always turn red and even purple. However, I don't experience broken blood vessels and I know how they looked and felt (they hurt! and they were tiny dots FYI). I think it's because we both have small frames and our skin when stretched is capable of the amount of blood flow it travels too. I have a personal trainer and he had once told me it's good wherever the blood travels because it means growth will occur.
As for your supplements they all stop working after your body gets used to it.. You have great results sweetie and I think you need to take a longer break from noogleberry because I believe one week is not enough. I recommend noogling off and on and see how it works if you don't feel comfortable stopping completely...
I had taken PM for like a year had great results- weight gain to 120 (Mind you I'm trying to gain weight), nice skin, healthy appetite, and big boobs (of course). But that was all unhealthy fatty weight and now I am trying to gain muscle weight so I had lost a lot of weight around my boobs. I am around 105 lbs now. I'm not on supplements anymore because I'm afraid of the bad side effects and future effects in case I had ever stopped taking the supplement ( I had BAD hair loss and acne after stopping PM). So be careful and cautious of the supplements you are intaking please! I noogle here and there but I need to gain weight in order to get my 32D back because right now I am a 32C which isn't bad at all after all the s**t I went through to get to the point I am today. Now, I'm not sure your views about gaining a little weight but I know it would help a little bit.
Good luck sweetie I can't wait to see more of your results!! STAY POSITIVE. Look how you progressed!
Hope my insight had helped a little
