I was standing for second rakah and got waswas if did my second sujud or not. I went back down to the sitting position and made up the second sujud. But I didn’t know if I had to say Rabbighfirli while sitting so I immediately went down to sujud without saying it. Is my prayer valid ?

If u suffer from waswas u should never ever e er go back to do something u thought u missed.
