If you just missed a period, you need to wait for 3-7 days to perform a urine pregnancy
test. Please do it with a fresh early morning sample of urine. If you want an earlier confirmation, you should go for the serum beta-hCG titres. Stress
, sudden weight disturbances, infections and certain medications apart from hormonal
imbalances can alter a period. If pregnancy is confirmed, you can go for a medical abortion
up to 63 days under medical supervision. When done under surveillance and with proper precautions, there will not be any future complications and conception in future is usually not a problem. Yet, if you do not want a child now, it would always be better to choose and practice some form of regular contraception
. Hope this helps.
