WANT TO KNOW WHEN TO TEST
IF YOU ARE PREGNANT?

Use this calculator to help you decide when to take your First Response Early Pregnancy Test. Avoid disappointment by testing before you have sufficient hormone in your urine.  Find out here when it is best to test!

Please note: These dates are approximate and are best used as a guideline for when to begin testing with the First Response Early Pregnancy Test. Additionally, these dates are based on a regular menstrual cycle. If your menstrual cycle is irregular, you may have more difficulty pinpointing the day of testing based on the calendar alone.
