Ok so

My period is late . I only thrown up one day because I also have the flu . And I have had nausea but when I did I never threw up , and my nausea were usually at night and it wouldn't last as long and I had for about 3 days then it completely stopped . I only threw up when I had the flu . And I am sexually active no protection nothing my boyfriend just pulls out and he pulls out way before his about to cum. But after he pulls out my vagina feels sticky . Idk . Could I be pregnant ?????
