Hi!
welcome to HCM!
If you read the instructions reading time is mentioned as 2min so if you read after a long time test is not valid. Although most home urine tests are pretty much the same, it is important to follow manufacturers' instructions.
You test it again early morning,with kit from other good company.
Susten contains progesterone and it supports the pregnancy & prevent miscarriage in early weeks. So the tablet is safe to take preferably in 1st trimester.
Hope this helps!
