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.
If your period is prolonged one month, which can happen even to women who normally have regular cycles who are sick or under stress, you may not ovulate until day 24. If this happens, you can get pregnant 4 days before you would expect to get your period, if your normal cycles are 28 days long.
