Depending when you put the condom on, there is a small amount of fluid called pre-cum that carries with it a small amount of fluid that has some sperm and possible infections (if the person has contracted any) that comes down to lubricate the urethra of the penis. It does this to help keep the sperm alive since sperm is actually quite fragile as it leaves the body and goes into the fluids of a female's vagina.

Therefore, the condom that you used possibly has this pre-cum in it. Now, that does not mean it caused a pregnancy because as you said, you used it again and withdrew the next time. This is actually a very good way to prevent pregnancy.

Most people don't recommend the use of a condom the second time but it is mostly because they fear that they will break. I think that it is smart to use it, because it does reduce risks and it is safer than using no condom that second time.

Congratulations on being so responsible.
