Is my buttock augmentation incision infected? (Photo)

I had a buttock implant augmentation and my daughter noticed fluid leaking down my buttock and an opening. There is no foul odor nor is it super nor do I have a fever. I am worried that it might become infected. Is there anything I can put on it ? Is it a normal healing process of this type of incision ? I did have stitches there but perhaps I was too active and caused the opening ? I am 3.5 week’s post op.
