Expert answer:

Only the relationships on the 13th and the 14th may have made you pregnant, there are good chances, yes, but this symptom has no meaning in the sense of mistrust of pregnancy. You may even be pregnant, but the most important symptom will be your menstrual delay, or you'll still have to wait a few days to find out.
