The party that did not respond has a default judgment against them. By saying it is interlocutory it simply means it is not a final judgment. Without actually reading the order there really isn;t anything else to discuss.
Although the average cycle is 28 days, it is normal to have a cycle that is shorter or longer. Girls usually start having menstrual periods between the ages of 11 and 14. Women usually start to have fewer periods between ages 39 and 51. Women in their 40s and teens may have cycles that are longer or change a lot.
Count each day until your next period arrives (when you'll begin at Day One again). You may need to do this for three or four months to get an accurate measure of the length and regularity of your cycle. The average menstrual cycle is 28 days long, but normal cycles can range from 23 to 35 days in length.
