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.
Implantation can start to occur as soon as 6-10 days after retrieval (I use after retrieval because embryos can be transferred on different days of development. Count the retrieval day as day 0). Five days after the retrieval a healthy embryo will have reached the blastocyst stage.
