Anne Ebeling: Are you, or aren't you? Finding out whether or not you are pregnant can be an overwhelming prospect. Just asked mom-to-be, Elizabeth Bulda. Elizabeth Bulda: I remember there were just so many different options. I mean, I was like, I don't know which one do I pick? I spent a long time looking, reading them and saying well, what's the difference, because if you're looking at them, you're like well, what's the difference between this one and that one and you're looking at everything and their prices are usually around the same. Some boxes have two tests in a box, three, one, so you know you kind of, there are so many different options. Anne Ebeling: Are all pregnancy tests created equal? Not really says OBGYN Dr. Suzanne Lajoie. Dr. Suzanne Lajoie: I think that there are a couple of pregnancy tests that do have some more accurate results or may get you sooner results. The FIRST RESPONSE Early Result is a pregnancy test that they have done some studies and it seems like it does have a greater sensitivity than some of the other pregnancy tests out there. The Clearblue Easy Earliest Results is also a highly sensitive home pregnancy test. So maybe one of those two would be a good one to start out with. Anne Ebeling: Be sure to read the instructions carefully. Some pregnancy tests allow you to pee in a cup and then hold the stick downward in the cup like this, rather than having to urinate on that small end. Elizabeth says this may give you some more control over the process. So how soon can you take it? Dr. Suzanne Lajoie: Every woman, in the ovulation, time of ovulation and fertilization and implantation and all these things are different. Every woman doesn't have exactly a 28-day cycle; the closer a woman gets to her date of expected menses or the date that she misses her period, the accuracy goes up, meaning that there are more positive tests the closer you get to your period and the day of the missed period. Anne Ebeling: That's why Dr. Lajoie says it's best to take a pregnancy test during the first few days of your missed period. Time of day also plays a role in the results. Dr. Suzanne Lajoie: These tests pick up HCG. So it's dependant on how much HCG is in the urine, how concentrated the urine is. So good time of day to do it is first thing in the morning when the urine tends to give it more concentrated. Anne Ebeling: The first test Elizabeth took that she wasn't pregnant. Elizabeth Bulda: We took it Friday night and it came back negative, and I was just like really? And I am still waiting and this was a weekend where I was having a bunch of college friends, their husbands, boyfriends, some of their children, and I remember I was opening up wine, drinking, and I was a little, I remember being a little hesitant, as I think I am still pregnant, like I had the feeling. Dr. Suzanne Lajoie: You can have a negative result and that can happen if there just isn't enough HCG in the urine. There could be a possibility that you're pregnant if you ovulated a little bit later than you calculated. So if that happens and you have a negative pregnancy test at home, you should usually follow that up about a week later and repeat it especially if you haven't gotten your period to see if you are in fact pregnant. Anne Ebeling: Elizabeth waited just a couple of days before giving in another shot. Elizabeth Bulda: I kind of waited the weekend and then on Sunday I started getting my period. We took another test on Sunday and I was pregnant. Even though we were like we were trying, so we knew I was not informed of birth control at the time, there is still a surprise like oh, it actually worked. It happened. We were both very excited. Anne Ebeling: Less common than the false negative is the false positive. Dr. Suzanne Lajoie: If you've had a recent pregnancy, it's possible that you could still have detectible levels of HCG in your urine and so that could give you a false positive. There are also some medications that are used for ferti
