I have an irregular cycle 40-45 days, i am 13 days late, i have experience cramps, nauseas in the morning and night time, i have a watery discharge for all 13 days, my breasts hurt and i can see my veins now, all test came back negative, am i pregnan?

Some thoughts...: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A woman who gets her normal regular period is not pregnant. If newly pregnant, the symptoms don't start until more than 10 days after conception. A home urine pregnancy test is very accurate by 3 weeks after sex, or 1 week after missing a period.
