Condom

be

I had sex wjth my boyfriend last night and we used a condom, he finished inside me with the condom on but when he pulled out he noticed the condom wasn’t on him anymore and when i went to feel the end of the condom was hanging out of me and the tip piece of it was inside me but the condom was still intact. I went to the sink and filled the condom with water to check for holes and there were no holes. Should i take a plan B or am I okay?
