I have had sex with my girlfriend just after her periods using condoms. Ejaculated within condom. Used new condom after each ejaculation. She gets her cycle super on-time. Now she got her periods started 8 days late. Her periods lasted the usual 6 days, flow was also as usual. A week after that she's complaining of weakness and dizziness, also got a fever for a day. Can she be
pregnant?
