[/INST] HI, A normally menstruating lady in fertile age. Having UN protected sex & getting delayed periods. The first diagnosis is pregnancy. Yes, you have possibility of pregnancy. But there are many other factors which cause delay in periods like-Hormonal imbalance due to psychological stress/ illness & medication/ thyroid or ovarian problems.  The pregnancy can be confirmed by blood Chat Doctor test (as urine test may have false result due to infection you had)/ USG scan of pelvis (after 5 weeks) Thanks. </s>
