Breastfeeding with saggy breasts!

Just the title. My LO is 7 weeks and I combine feed. I have saggy breasts with right breast bigger than the left. Its difficult to breastfeed because I have to hold my breasts otherwise it unlatches or drags down the nipple. Also, I can’t think about lying and breastfeeding. It just doesn’t work. Anyone else with saggy breasts and breastfeeding? How do you do it?
