Scared

So I am day 4 of my cycle.I had sex with my bf two times both with condom+ pull out.After the first time we both washed ourselves and then we had sex again.It was longer and after he came I saw that there was very little sperm.I panicked and filled the condom with water-no leaks.I asked him and he told me that he did orgasm but because he pulled out he needed a couple more strokes for the sperm to come.I know that if the condom is not broken, there is no way for the sperm to come out of the condom.Am I safe?
