State law differs regarding DBA publication. Generally speaking, when publication is required, the DBA statement must be published once a week, in a specific newspaper that posts legal notices, for four consecutive weeks. Publication is included in the LegalZoom filing process.
If you are not having a period or you are having an irregular cycle, you can still get pregnant because ovulation occurs before your period, and ovulation can restart at any time. Young women can even become pregnant before their first period. There are no concrete physical signs of ovulation, so you could be ovulating and not know it.
Patients who become pregnant without any monitoring (ultrasound, ovulation prediction kit, basal body temperature, etc.) generally use menstruation to determine due date and age of the pregnancy. The average human pregnancy lasts 40 weeks from the first day of the last menstrual period to the day of delivery. This assumes that ovulation occurs 14 days after the first day of the period. Accordingly, this age, which is called gestational age, is 2 weeks greater than the embryonic age.
