Not Enough Tightening and Skin Removal from Tummy Tuck?

It is difficult to evaluate your concerns without examining you directly. If you are two months postop, it is possible there is still swelling present that may subside. Also it is possible that there is fat present that might benefit from liposuction. It's usually a bad idea to perform aggressive liposuction during a tummy tuck, especially in the central abdominal area, due to a high risk of complications.
In general, if a full tummy tuck was performed, your concerns sound a bit unusual. If a mini tummy tuck was performed, that could explain the upper abdominal bulge (if the fascia was not tightened) or the extra skin still present.
In some patients who have had a great deal of weight loss-- and 5 full term pregnancies could fall into that category-- the elastic fibers of the abdominal area skin are stretched and ripped. It's not possible to restore those ripped elastic fibers, so there may always be a slight amount of looseness when the patient bends forward that it may not be possible to correct.
Your board certified plastic surgeon can hopefully answer these questions for you and guide you through any additional procedures that may help you further, if any are even warranted.

Thank you for your question. To provide a valid medical opinion I will need to see pictures of you body from different angles. I would suggest to be treated by board certified plastic surgeon with experience in this procedure, to get the best desired results.
Respectfully,Dr. Emmanuel Mallol Cotes.-

Skin elasticity is a major factor in determining the final result. Pulling tighter is not always the best solution because pulling too tight can cause the skin to die. So it comes down to a judgement call.
