Self-examination of the uterus does not give a complete picture of its condition, but will only help make some assumptions. Perhaps this is the only positive side of this procedure. But there are many more negative aspects. This is also the possibility of infection, trauma, which threatens inflammation, complications that lead to infertility.
A photo of what the cervix looks like before menstruation and during pregnancy cannot help analyze the condition of the organ. You should be guided only by tactile sensations.
If you have any questions, you can always ask your gynecologist. If necessary, a woman can conduct an independent examination of the cervix, but this should be done only in extreme situations and no more than three times a week.
To determine the condition of an organ, considerable experience is required, which means that in its absence, the examination will be uninformative and will not yield any results. Only an experienced doctor is able to recognize changes, evaluate them and prescribe additional examination methods, because the position of the cervix is constantly changing by day of the cycle, and these features must be taken into account.
