TTC after nuva ring

Hey everyone so I stopped using my bc after my period i had bled i think the 14th or 15th to the 19th of june & i put my ring in the 17th or 18th to stop my period but then I decided that I didnt want to be on it anymore so I took it out the 21st & immediately bled the 23rd-26th ig my breakthrough already. I started taking prenatal vitamins the 21st when I stopped as well and I had sex multiple occasions with him unprotected but I really noticed he orgasmed the 3rd of this month. How long should I wait to take a test & is there a possibility I could be pregnant?
