A woman can tell if she is pregnant a week after ovulation, and if there is no way to know when she is ovulating, the easiest way to find out is to see if she has a period. If you don’t have your period when it’s due, the first thing to do is to wonder if you’re pregnant, and you can test yourself with your first morning pee. If two bars appear, you are pregnant. If you know when you are ovulating, you can take a blood test at the hospital one week after ovulation. This is because at this time you can’t detect it with your own urine, but you can find it out with a blood test because the hormone levels are higher in the blood at this time. The blood test will not only tell you if you are pregnant, but it will also show you the number of digits, so you can tell if the baby is developing normally.
