Going up on my estrogen!!

Hii so I just had my follow up appointment with my doctor and I asked about increasing my E and she said it be a good idea to try it out and if I don’t like before our next appointment to go back to 4. My levels are all good 50 spiro twice a day and my T level is 15 and my current estrogen is 2mg twice a day with my E level 147. I’m noticing changes like softer skin, little body fat changes, sexual changes, and some breast development and I ofc want my boobs to grow more but I am nervous for going up! What are your thoughts 🖤
