Frequently Asked Questions
Your answers to some of the most common questions regarding app functionality and company policy
Our application aggregates multiple parameters to determine the most favorable days for conception.
As you may already know, the day of ovulation and the five days preceding it are the most suitable period for ovum fertilization – that is because the sperm remains viable inside female body for as long as five days after sexual intercourse.
A 100% accurate ovulation day prediction is possible only with clinical equipment and the use of ultrasound. Nevertheless, by collecting and organizing information, the Selin application can determine ovulation days with a high chance of accuracy.
The application monitors the fertile window. Keep track of the highlighted dates in the calendar, which indicate favorable period for conception. Naturally, the day of ovulation is the most favorable one.
By regularly including additional parameters, you can make the forecasts even more accurate.
Even if conceiving a child is not part of your plans, observing the menstrual cycle can provide invaluable data that will help you, for example, to avoid an unwanted pregnancy, or keep track of the symptoms for greater awareness of your health.

Choose food, or what ingredients are best kept apart?
The cuisine, especially the traditional Slavic one, is quite eclectic in nature. But not everyone knows that some ingredients we use to cook are simply incompatible. This is due to the fact that the creators of the dishes were mostly concerned with the palatability of the food, and not the effects it had on the human body.
How simulating an orgasm harms you
Simulating an orgasm, unfortunately, is quite common. For some, it’s an exception for situations when you’re not in a mood, but he simply won’t let you be. For others, this is a new norm. There can be many reasons for this – from a temporary decrease in libido due to hormonal shifts to permanent frigidity.
Is alcohol allowed during pregnancy?
Drinking alcohol during pregnancy has long been a subject of controversy, both among scientists and common folk alike. Obviously, no mother in her right mind will indulge in drunkenness during a period of pregnancy, and putting her pregnancy at risk. However, the notorious “a glass of wine is ok” still causes a lot of controversy and skepticism.
