They already told you very useful information and I'm going to try to help you with my experience 
I have been noogling for 2 months without any results. I couldn't get any swelling, even after 5 or 6 hours of noogling. Then I bought Eveline Slim Extreme 3D push-up serum, it contains volufiline. I bought it on discount for 3.50$
And after 3-5 days, for the first time in my life, I could see that famous luteal swelling. Then after few days, my menstruation came and I've lost everything. Next cycle, I have been using Eveline serum and of course noogling, but much less then before and my sweling, unfotunately, was much less then before 
And sometimes I had the same feeling like you, that thay were even smaller after noogling. Then after my menstruation, I've lost that tiny sweling and my measurements were the same like always, but somehow, I didn't look so flat like before 
So, in my fourth month, I decided to noogle more often. I did it every day for between 1 hour and 6 hours at the time, with less presure than before because I read that less presure is actually more. After applying less presure, I've never had the feeling I was talking about, that they are even smaller after noogling. It helped me alot. Before this, my goal was always to fill the cups as much as it is possible without getting the red dots. Now I'm pumping to that point, and when I reach it, I release a bit of air. That's it. And in the middle of that cycle, I've started listening to breast enlargement ringtone. My swelling was WOW And after my menstruation, I've lost that swelling, but there was something visible, I've got 2 cm 
Now, in my fifth month, I've added this massage https://www.youtube.com/watch?v=wdAHZdQxPkM and for the first time in my life I can experience some tingling and some pains in my breasts. Soon, it's going to be half of year since I started this program and I will have AT LEAST 3 cm more than 6 months ago 
I'm so so so happy ))
Why? Because I was already on PM, for one WHOLE year while doing dear massage, with no results, not even 1 cm, not even temporary swelling, nothing. So I know how you feel But keep going until you find something that works for you. We are all different.
I hope this was helpful.
