I would really appreciate some advice . My period is never later than day 30 , today am on day 33 and still nothing . I took a blood test yesterday and it was negative . Can I still be pregnant ? I did have intercouse two days during my fertile window . I'm stressed now which I wasn't before so maybe that's why I haven't gotten a visit from my monthly friend .  I also traveled to Orlando from NYC this weeke and my grandmother said that could be another factor of why am this late . I'm about to be one week late and this has never happen to me . Help help help !
