What could happen?

I got the Nexaplanon implant February 27th, and for the first time ever, my SO came in me. 3 times. This all happened on Sunday within 3 hours. My period was just ending (little blood, spotting) on Sunday. I know this is silly to ask, but could I get pregnant? It's been almost a month since I got the Nexaplanon, so I would think it would work. But my friends say I have an increasedR chance since he came in me 3 times. Help guys!
