Post IVF ovary pain

When I woke up after the egg retrieval (ER), the bottom right side of my belly (where the ovary is) was paining. I was later advised it may be because there were more eggs retrieved from my right ovary and that was why I was sore there. Anyway, the dull pain recurred at times for the next 3 months post ER. The last time I experienced it was in December 2014. This month January I haven't had any ache/pain in that location. DH was of the opinion that it only takes a month to recover from the ER. What do you think? Has any of you experience this after your IVF ER? Please share your thoughts or experience.
