edit.....

 I wish you´d told me this before because I´ve used my leave. Next month it´s Bayram and I´m going to my mum´s. I can take a second leave in the winter ,so if you want I´ll come without thinking.

My try

My try:

 I wish you would have told me this earlier becuse I´ve already used my holiday. Next moth there are holidays here and I will go to my mother´s. But I can take holiday again in winter. If you want I can come then even without hessitating.

thanks  a lot!!!
