Positive Pregnancy Test

If the pregnancy test is positive, the provider should assist the patient in estimating gestational duration (age) so that appropriate care and counseling can be provided. 

Pregnancy dating can be more difficult if the patient does not know their LMP or if they have irregular cycles. Any hormonal contraceptive use or gender-affirming hormones in the last cycle, including emergency contraception, make the LMP unreliable. If the person is unsure of the timing of their last normal menstrual period, a pelvic examination or pelvic ultrasound (more accurate) can help assess gestational age.
