Is pregnancy possible here? Involved.

Yesterday, my boyfriend and I had some physical intimacy, but we both remained fully clothed throughout. He was wearing jeans and underwear, which he did not unzip or remove at any point. I was also fully clothed, but he inserted his dry middle finger about 1 cm into my vagina through my jeans and underwear. Each time he did that, I immediately removed his hand. We repeated this a few times. Before touching me, he had touched various parts of my body and we had also sucked and licked his fingers, but he did not touch his penis at any point during or before this. He assured me that he had taken a bath in the morning and hadn’t touched himself since. There was absolutely no semen exposure, no genital-to-genital contact, and no ejaculation involved.
