Mom:
At this point, you may not even realize that you’re pregnant. If you have a sneaking suspicion, you’ll probably take a pregnancy test, which measures your level of hCG — a hormone released only when a blastocyst has attached itself to the uterus.
At the very start of pregnancy, there isn’t a lot of hCG present, so it might take a few more days before a pregnancy test will give you the good news! You should generally be able to find out around the time your next period is due, about four weeks into the pregnancy, but if your test comes back negative, you may want to try again in a few days.
A blood test can detect pregnancy earlier than a urine test.
Certain women can sense that they are pregnant. For others, it’s a complete surprise until they’ve missed their period and get a positive test result.
