Pumping-cracked and bleeding nipples??

My supply was amazing for me considering I didn’t produce much with my son and then I forgot to pump for a day and that all went out the window so now I’m pumping every few hours to try to bring my supply back up… and I’m noticing that my nipples are cracking and bleeding. I know the flange is the correct size and I’m pumping correctly, any idea what to do to avoid this cause ouch. 😩 also nowhere in town has lanolin cream so I need ideas to heal this!
