Perineium is now more separated than it was before my Perineoplasty - why did this happen?

I had a perineoplasty about 6-7 months ago and now out of the blue it seems that it has gone right back to how it was pre-surgery and even worst. My vagina opening is back to pre-surgery and my perineium is now more separated than prior to surgery. Why did this happen? Followed my surgeons advice on healing. No sex or exercise for more than 3 mos. Things seemed to be ok until the last week.
