My Teddy had the urge to potty whenever he thought he was going to be alone (which was really just alone in the house, while I was outside doing yardwork). I would put him in his pen and walk out for 5 minutes and then go back to change his poopy pad. Then we were set.
As Gracielove indicated, small pups have to go often, especially when they are only 16 weeks old. Anything that causes excitement or anxiousness will make them want to go.
For a potty schedule, you can count on your pup having to go whenever she wakes up from sleeping/nap, after she eats, after she plays, and after anything that causes excitement and anxiousness, and probably in between.
Are you still using the potty patch or did you decide to outdoor train only? My boys are pad trained in addition to outdoors. For a puppy, confine to a smallish area like an xpen with the pad/patch in one corner.
