Dry mucous membranes: When the mouth or nose gets dry normally present bacteria types can change which in turn may effect taste and smell. Some medications and allergies can cause these findings as well. An autoimmune process called Sjogren's can do this and can be serious.
When Does Implantation Occur? Implantation typically occurs 6 to 10 days after ovulation, or day 20 to 24 of a menstrual cycle. However, it can happen a few days earlier or later. In an average 28-day cycle, ovulation occurs on day 14 with the first day of a woman's period being considered day 1 in a cycle.
After the implantation, these early signs will disappear. Implantation occurs around six to ten days after ovulation. If your cycle is regular (i.e., 28-day cycle), you will experience implantation bleeding and cramping in the third week (i.e., around days 20 to 24), a week or so before the missed period (1).
