I salute you, Photo_Gaz, for persistence and determination. Keep asking questions and you shall be answered, though the more carefully written and precise the question the better the answer.
Most 35mm cameras have counters arranged so that the two shots you make to advance the film past the exposed leader will bring the counter to Number 1.
So I suggest for your next roll, you make those first two shots with the lens cap on, so there will be no confusion about what you (and possibly we) will be seeing. Then make a note of the subject matter of photo Number 1, 2, and 3.
Then when you develop the roll, you'll see where the photos begin, and you'll have a procedure that you can follow to guarantee yourself getting unobscured shots at the beginning of the roll.
At the end of the roll (say a "36 exposure" roll), you'll feel some strong resistance as you advance the film around Number 35 or 36 or 37. Do not force the film advance at that point (or around 23, 24, or 25 just in case you actually put a 24 exposure roll in). Rewind the film at that point.
Likewise, when you get to shots Number 33, 34, and the last ones, make a note of your subject matter of each shot, so you'll know what you got and what you should have gotten.
When loading for development, cut the film off the film canister reel just a fraction of an inch, say a centimetre, before the tape. If you do this, there will usually be about 3 to 5 centimetres of blank film at the end (clear, no image, but with edge numbers or edge film type markings, more or less).
