It only takes one sperm (in semen, all the time) to trigger pregnancy and it has been documented from exposure at any day of a cycle including during menses. While it may be #2, this becomes a legal issue and you could get a big surprise at birth. You can have a NIPS test at 8-10 weeks and compare the findings to known men to find the answer.

Agree with Dr. Ferguson. You can keep guessing or get tested for a definitive answer. Pre-natal Paternity testing: https://americanpregnancy.org/paternity-tests/non-invasive-prenatal-paternity-test/ Wish you good health and a healthy baby.
