Unwanted type of emergency medicine is given within 24 hours only to avoid unwanted pregnancy
giving her just before period may cause more harm because this tablet is loaded with hormones and it can delay normal period
wait for date and get tested and treated accordingly.
Urine pregnancy test should be done 10 days after missing your period. For example if your date was 10th, then do the test on 20th. Before that it can give false negative or false positive test.
Faint second line means that the test is positive
if still want confirmation, get blood tested for beta hcg hormone which is positive before the due date of period.
Once the test is positive, it's always positive after delivery also, during post partum period
by 3 month test for pregnancy is positive and get ultrasound done to confirm the dates, months of pregnancy.
It's a pity that emergency medicine is used for routine prevention of unwanted pregnancy
these pills are loaded with hormones which can make period delayed erratic irregular or heavy
and when the woman wants to have a baby, she has to visit innumerable infertility clinics
take care and don't give her more hormones
let nature work for making period regular.
Firstly trust your doctor. Secondly urine test maybe delayed in such cases. Thirdly beta hcg levels in blood rise after implantation of the fertilized egg. Blood test for beta hcg can be helpful and do discuss with the treating doctor and don't get confused.
