Yumurtlama Hesaplama is a free lifestyle application for Android developed by Aslıhan BAYBAŞİN. The app helps women determine their ovulation date, which is crucial in calculating the best time for pregnancy. For women with regular menstrual cycles, ovulation occurs about 14 days before their next period. This app provides a practical and easy way to determine the day of ovulation by counting 14 days back from the first day of their period. The app suggests that engaging in sexual intercourse 2-3 days before ovulation and 2-3 days after ovulation can increase the chances of becoming pregnant. However, daily intercourse is not recommended as it can reduce sperm count. The app also provides examples for women with regular and irregular menstrual cycles. Overall, Yumurtlama Hesaplama is a useful tool for women who are trying to conceive.
