Surprise! One week pregnant is actually not pregnant at all. Say what?!
Most OBs count pregnancy starting from the first day of your last period. That’s because ovulation and conception are really tough to pinpoint, but the physical signs of menstruation are much easier to spot. So in doctor speak, 1 week pregnant means you’re on your period and not yet pregnant. You won’t actually conceive your baby until week two or three, depending on the length of your cycle.
If you’ve just found out you’re expecting, you might think this is your first week of pregnancy, but you’re probably around 4 weeks pregnant. Yes, already! (Your OB will give you a more accurate estimate when you go in for your first prenatal appointment.) Skip ahead and check out week 4.
Think you’re 2 weeks pregnant? You might not be. Here’s why.
Most OBs count pregnancy starting from the first day of your last menstrual period (LMP). Yep, that’s a week or two before you even get pregnant. We know it sounds totally weird, but it’s more accurate for doctors to estimate a due date this way.
So if you think you conceived about two weeks ago, you’re probably at least four weeks pregnant—maybe even five. We give you permission to skip ahead to week four.
If you really are in the second week of your cycle and are trying to conceive, we’ve got some advice right here for you.
Sperm met egg last week, and voila—you’ve made a baby! It’s so ridiculously early that when you’re 3 weeks pregnant, you may have no idea that you’re actually pregnant. Conception just happened a few days ago, and there probably hasn’t been time for you to miss a period yet at week 3 of pregnancy.
Congratulations! If you know you’re 4 weeks pregnant, you found out the news earlier than a lot of women do (because you took a test as soon as you missed your period, or even a few days before, instead of waiting a bit)—and you might be totally excited, or you might be getting used to the idea of having a baby. Either way, you may not be feeling any different (for now, at least), since early pregnancy symptoms don’t always kick in right away. Definitely celebrate this amazing news with your partner, but you may not want to tell the whole world… just yet. Your first call at week 4 of pregnancy should be to your doctor to schedule your first prenatal visit, where he or she will confirm your pregnancy with a urine or blood test.
