Severely Engorged

12 weeks pp 🫶🏽 I bf baby early evening, pumped on opposite boob, then on the boob he had nursed from. I was exhausted and fell asleep. Been up since 2:30am, it’s 6:40 rn have pumped for 1:30hrs!! 😭😭
It took two sessions for my left boob to express. My right is severely engorged; only have gotten two ounces of foremilk; I usually get anywhere from 7-12 ounces on the right one alone.
Waiting for Target to open at 8 am to purchase a manual pump. Also baby can latch and help mama out, but I would like to soften them a bit bc if not until they soften latching could be challenging for him and painful for me. My husband suggested taking my sized flange out and using a bigger size to see if it helps draw in more of the boob since my right boob is rock hard up until the areola.
Suggestions? I’ve cried already… Just trying to stay calm I know it will solve somehow
