Low supply in one breast

abnormal06

Hi ladies! This is my first post, major lurker:)

SO I have exclusively breastfeed my son for 3 months and have always had a lower-ish supply on my right breast. Well now it is practically empty feeling. Even when I feed my son on that side he gets upset and frustrated (crying). This has been going on for a couple weeks. The pediatrician said I could just supplement if needed, so I did. Alittle. The. It seemed he hit a growth spurt in which I felt like my body couldn't catch up or something. Then I got the flu( I don't know if that has anything to do with it too)  Did I mention my left breat looks smalle than my right? Anyone else gone through this? Any suggestions for trying to get my supply back. I would like to be able to breastfeed. Kinda feel like a dried up lady. I would love to alternate feeding. Nurse bottle nurse bottle etc. 

Any thoughts/ suggestions would be greatly appreciated.
