Помогите склонить предложение "Я пошла с мамой за покупками" в 12 временах.

I often go shopping with my mom.

I am going to the shop with my mom at the moment.

I have gone shopping with my mom already.

I have been shopping with my mom since morning.

I went shopping with my mom yesterday.

I was shopping with my mom yesterday at 5 o'clock.

I had already gone shopping with my mom.

I had been shopping with my mom for 2 hours when you called.

I will go shopping with my mom tomorrow.

Tomorrow this time I will be shopping with my mom.

I will have gone shopping with my mum by next month.

Next year I and my mom will have been shopping together for 10 years. (В следующем году будет 10 лет как мы с мамой ходим за покупками вместе - нужно добавить слово "вместе", а то звучит коряво)
