Anytime you have unprotected intercourse, there is the risk of pregnancy. Even if you didn’t ejaculate inside, you may have leaked some pre-ejaculatory fluid into this woman’s vagina. Pre-ejaculatory fluid (precum) may contain sperm, which could result in pregnancy.
If you had unprotected intercourse and the woman did have two normal periods after that, then she did not get pregnant from that incident. This is assuming that you did not have any further unprotected intercourse with this person. The majority of women miss their next period and continue to not have periods until the pregnancy is terminated by either abortion or delivery. While abnormal spotting can occur in early pregnancy, it is not common, and does not occur on a regular basis.
If paternity of this pregnancy needs to be established, for either personal or legal reasons, you may want to consider a paternity test in the future.
