Ejaculated sperm remain viable for several days within the female reproductive tract. Fertilization is possible as long as the sperm remain alive — up to five days. You don't know exactly when you ovulated, so a paternity test may be necessary to determine the father. Use contraceptives. ref: https://www.mayoclinic.org/healthy-lifestyle/getting-pregnant/expert-answers/pregnancy/faq-20058504#

Only can DNA test of the baby and one of the men can tell you the accurate answer. By the timing, your boy friend is more likely the father but in reality, ovulation can happen early than the expected time or sperms can be alive up to five days in your genital organ.
