Hi!
I look back on my start page and it turns out to take me about 2 months to fill the domes. I start with the M domes, then at the end of March I started using the L domes, for about 30 mins per day. One month later one of my L domes was broken so I had to use M & L inter-charged because the M couldn't cover all my breasts. At the end of May, I started using 2 L domes after sessions with M domes. Recently, I only use the Ls.
I have never fill the Ms but today, for the first time, I completely fill the Ls. That's weird!!
