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.
It is possible to get pregnant soon after your period ends depending on how long your bleeding lasts, and when in your menstrual cycle you ovulate. If your periods are long, by the time it ends you may have few or no days left before your fertile days begin if you ovulate during the average days 12 to 14 of your cycle.
