I tried them once. And yes, I didn't leak. But when I went to extract it, the tampon was stuck. I almost had to use a block and tackle to take it out. And when it came out, I felt like I pulled some of my still healing tissue out. It was incredibly painful. It had adhered to my vaginal tissue. I only had it in for a few hours.
Use a pad. I used super absorbent over night pads. They provided good protection and a bit of cushioning when I sat.
My surgeon suggested using regular gauze bandages rolled up into a tube and inserted. They won't adhere to the vaginal walls and provide a modecum of protection. You still have use a pad, but it won't saturate as quickly.
A menstrual cup may work, I've never tried one. But it would collect any drainage from bleeding or dilation. And they don't adhere to your vaginal walls.
