firstly congratulation on getting 11 eggs at EPU.

with regards to OHSS it really is so unpredictable and how long each person takes to recover is just as hard to determin.

For me i didnt have much pain until two/ three days after EPU and that was when they discover my ovaries had swollen to over 12cm each. i was bloater for several days and although i took some pain relief found that rest really was the best medicine.

I hope that you are back on your feet ASAP and that you can still get away and continue to rest once you arrive.

Read a good book and continue with the water intake. you should start to feel relief once af arrives.
