What should my husband and I be prepared for re:side effects?

My husband (33M) and I (33F) are about to start our first round of IVF. I have severe stage 4 endometriosis and DOR (with an AMH of .26).

What would you say my husband (and myself, honestly) should be prepared for mentally and physically? I'm talking symptoms of the medications or procedures, side effects you weren't prepared for, things he should expect from me? Will my emotions be super heightened, will I be sick, etc. I'm not talking about "prepare for it not to work" or "may need multiple cycles". We can read all the educational literature we want, but it's not the same as other people's experience with side effects and symptoms. I understand everyone is different, just trying to prepare ourselves. Thank you!
