My period is usually normal & I had sex before my period . He did ejectulate in me . So yesterday my period was supposed to come on , it didn't , today , it still hasn't . But , I thought that if this happened , you wouldn't miss the upcoming period , you'd miss the next ones ... the future ones . I don't know . Could I be pregnant ? I feel fine . It's been 2 days . When should I start feeling my first symptoms ?
