I am hanging a curved shower curtain rod to replace a spring loaded/standard curtain rod. The rod came with drywall anchors (3 each side) and I started drilling the holes for the anchors. First hole, no problem, 2nd and 3rd holes appear to have hit a stud (much more resistance and wood chips). As you can probably tell I am very much a novice with home repairs, and my question is can I use the drywall anchors in the stud? I was able to get one anchor to easily fit in the first hole, but I can't get them in the other two holes even though they were made with the same drill bit. Any suggestions? Can I use wood screws for the 2 stud holes and keep the drywall anchor for the other? Can I make the stud holes larger to fit the drywall anchor?
The three holes are in a triangle shape: 2 at the top about an inch apart and the 3rd below about an inch in between the top holes.
