Hi Rosaly!
Depending on how large you want to get, I would definitely recommend getting the largest domes that you can fit onto your chest, no joke. Work with Lucy the admin at Noogleberry via email to get some good suggestions. I am a bit larger frame than you, I am 32" around my ribcage, and I easily switch back and forth between a contoured large and a contoured extra large. If I had known going into this how the width and shape of the breast is affected by the dome circumference, I'd have started with the extra larges and saved the rest of the money.
I have to agree with James, there may be something to this Noogling irregularly to get good growth. Jenniferlove might not agree, as she Noogled regularly and has PHENOMENAL and super inspiring results to show for it, but I am finding that my swelling is better and hanging around longer if I only massage a couple of days a week and then massage and Noogle the rest. In fact, for the next few weeks I'll be performing a little enforced experiment by Noogling only once a week and massaging the rest - work does tend to get in the way of NBE sometimes!
As far a swelling goes, there are many folks, myself included, who did not swell at all in the beginning. Frustrating does not even begin to describe it, but there it is. The fact that you're swelling even for just a little bit is a really good sign, so keep at it. Pretty soon you'll be swelling more, for longer periods of time, and then, one fine day, you'll realize "Hey! I haven't Noogled for, like, two days, and my swelling is still here!" That's the goods for sure.
I do use a volufiline cream, but not religiously, as I happened to have some left over from a while ago and stopped using any herbal supplements for the time being. Ironically, since I've stopped using any BO or PM or Fenu or anything like that, my Noogle and massage swelling is rather impressive, for me anyway. I am using Vitex and Maca to try to get back into balance, and drinking a little spearmint tea, but nothing aggressive at all.
Xo, Soli
