It is tough, it's a git to add weight to so even worse for a woman, that's no reason not to do it. My max is 60kg+ and adding 2kg would take me many months, so consider how much more a 2kg increase is for you as a % of your max. the upside is your a noob so will make gain quicker at first.
Stop hopping, there's no reason for it and it is probably making your form bad. If you can't get the weight moving without it then lower the weight.
