The desire of the expectant mother to determine who is the father of the child is quite understandable. After all, I want to share the joys of pregnancy and care for an unborn baby with a man who will take a direct part in this. However, if you have had two or more partners, you may have doubts about paternity.
Instructions
Step 1
You can determine the father of the child by the expected date of pregnancy. To do this, remember the last time you had your period. If you keep a calendar where you scrupulously mark the onset of your period, great, it will help you get the exact date.
Step 2
To determine the date of conception of a child, you also need to know the length of your cycle. For most women, this period is 28 days, but it can last from 21 to 35 days. During ovulation, a mature egg is released from the ovary, ready for fertilization. This usually happens 14-15 days after the onset of menstruation. For girls with a non-standard cycle, this period must be calculated individually. Ovulation is a good time for conception. However, one should take into account the viability of sperm in the female genital tract, as well as the fact that conception can occur not only on the day of ovulation, but also two to three days later. In total, the onset of pregnancy occurs in a period of six to nine days. The dangerous period begins three days before ovulation. If at this time you had contact with only one man, then he is the father.
Step 3
An even more accurate age of the fetus will be told on ultrasound diagnostics. It makes sense to do it for a period of ten weeks. The doctor will tell you how many weeks the fetus is, so you can more accurately determine the day of conception.
Step 4
The most accurate determination of who is the father of the child can be done using a DNA test. You don't need to wait for the baby to be born for this. The doctor will take the necessary genetic material from the amniotic fluid. Also, the research will require the DNA of the alleged fathers of the child. After finding the matching genes, you will be told which of the men will become the dad. Such a diagnosis can be carried out as early as the ninth week of pregnancy.
