R sided hemm. ovarian cyst 46.6mmx41.9x45.9 volume 46.9ml. history endoand decreased ov reserve n/v, pain how long does it take to absorb?waiting to do ivf

It may not absorb: If it is truly a hemorrhagic cyst it should resolve in 4-6 weeks if not sooner. If it is an endometrioma, it may not resolve on its own and may require surgery to improve your ivf outcome. I recommend you talk to your reproductive endocrinologist about strategy here. You don't want to lose time if you have diminished ovarian reserve.
