I'm 22 days delayed, and we had intercourse today, is there a big chance that i'm going to be pregnant? today is my ovulation day

Hard to guess: 22 days? It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result by about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. That said, having one's normal regular menstrual period means not pregnant.
