I m/sturbated twice this ramadan..

I swear I genuinely dont want to and I always regret it afterwards, but it happened twice so far. I am scared and i fear that my fasting will not count for those two days. I prayed afterwards, regretting it and asking Allah for forgiveness, but i am scared. What if he doesnt forgive me? What if its not even the Shaytan, but my heart that is evil. I hate that i do it. I want to stop.

What did you do to stop your urge?

And do i have to repeat my fasting for two days after ramadan? Please help
