Re: Is Fact Plus a good brand?
You can test the day you were expecting your period. Some tests are now sensitive enough to detect HCG a few days before your period is due. If, however, you have irregular cycles and you're not sure when your period is due, you can test 19 days since the last time you had unprotected intercourse. Remember though that HCG production varies from one woman to another...that's why even if you get a negative on your fisrt try, try retesting in 3 days...HCG levels double every 2-3 days. If you don't want to waste your money, especially if the test is not highly sensitive it would be best to keep it for the day you were due for your period or a few days later.
