Risk of pregnancy. Or i am overthinking?

I had sex, and my partner didn't ejaculated inside condom nothing come out of his penis, because of durex extra time having some kind of lubricant benzocaine inside condom. After that he threw that condom and washed his My boyfriend washed his penis with water before and try to excite it to be straight and then washed hand and again wear new condom but during wearing the condom was slippery and not easily coming down so sometimes the finger touches the below skin of penis during wearing that condom. And he even again didn't ejaculated inside condom. My 1st day of period was on 23 August and it ends on 25 August and i had sex with him on 29 August. And my period cycle is of minimum 30 days. So is there any chance of pregnancy? Should i take emergency Contraceptive pill? Or i am overthinking? This is my first time. I was virgin before . Please tell me doctor. Overthinking.
