Intrauterine insemination (IUI) is a method of overcoming infertility. Many women wonder how soon they can take a pregnancy test after IUI. There are several factors that will influence your decision, but most doctors recommend a wait of at least two weeks.

During IUI, washed sperm is inserted through the cervix into the uterus via a catheter. It is typically performed when there is a problem with the man's sperm or the woman's cervical mucus. Introducing the sperm directly into the uterus bypasses both of these problems. IUI is also used when single women want to have children using donor sperm.

The recommendation is to wait at least 14 days before taking a pregnancy test after IUI. This is how long it will take most women to build up enough of the pregnancy hormone in their system to test positive. It is sometimes possible, however, to get a positive result sooner. Sensitive tests may be able to detect the hormone as early as nine days after IUI. Women testing that early should keep in mind that they may get a false negative result.

For some IUI cycles, a trigger shot of human chorionic gonadotrophin (hCG) is used. This helps trigger ovulation in order to time it right for the IUI procedure. Since hCG is also the hormone that makes a pregnancy test positive, women who have had the trigger shot should wait longer before taking a pregnancy test after IUI. It usually takes eight to ten days for this to happen, but can take up to 14 days or longer. Some women take an inexpensive pregnancy test every day until it is negative, which means the hCG from the shot is gone and future tests will be accurate.

If you take a pregnancy test after IUI before the 14 day mark, you may get a false negative. This happens when you are pregnant but there is not enough hCG built up in your system to turn a test positive. Different tests have different levels of sensitivity. Those that say you can test before your period are the most sensitive, but you can still get a false negative. If you have gotten a negative pregnancy test after IUI but still have not gotten your menstrual period, wait a few days and test again.

For the most accurate results, pregnancy tests should be taken using the first urine elimination of the day, but if you forget you should hold your urine for at least four hours before testing again. If you have waited at least 14 days after IUI to test and you get a negative result but still have not gotten your menstrual period, make an appointment with your doctor. He or she will probably do a pregnancy test using a blood sample, which detects lower levels than urine testing.

Today is my 17th day after IUI, but the HPT result was negative. I had taken HCG injections before having IUI. I haven't got my periods, either. I am very confused. I don't know what should I do. Please suggest to me what I should do.

I've heard that you need to wait up to four weeks after having sex to get a pregnancy test, depending on what types of pregnancy tests you're using. I guess the time difference is because IUI puts the sperm right into the uterus while free floating sperm can stay alive and ready to impregnate for up to a week after the deed.

@irontoenail - I think it can be difficult for people to stop thinking about it because fertility treatments of all kinds are expensive. It's easy to say, oh you can always adopt, or you can always do IUI or IVF treatments, but if you are an average family, you probably aren't going to be able to afford too many of those.

So, every one of them counts. Adoptions can be upwards of $40,000 depending on how you do it. And fertility treatments often have awful side effects, so on top of everything else you're going to be moody from those. It's not as simple as telling something they shouldn't be worrying about how soon can I take a pregnancy test. There are a lot of different factors.

I know it's easy to say it and less easy to do it, but you really should try to relax and not worry too much about the pregnancy test. Stress and worry really do stop you from getting pregnant. The number of people who stop trying and finally manage to get pregnant because they aren't putting pressure on themselves anymore is fairly high.

If you're stressing over when to take the pregnancy test, you're doing it wrong. Sit back, relax, continue to have fun and don't worry so much.

Again, I know it's easy to say, and less easy to do. But you'll have children for a long time once you have them. Waiting an extra week for the pregnancy test isn't going to kill you.

I didn't have IUI with my first pregnancy--I'm looking into it now as pregnancy #2 doesn't seem to be happening--but I did use an ovulation predictor kit. The one I got came with a bunch of pregnancy test strips as well as the ovulation strips. It was a much cheaper alternative to buying so many of the sticks--although the disadvantage is you have to pee in a cup and dip in the strips. If I do go forward with the IUI, I think I'll try to get a bunch of those strips again so I can take as many as I want until I finally get that real positive pregnancy test.

If you're wondering when to take a pregnancy test, keep an eye out for implantation bleeding. Not everyone experiences it, but it's a nice clue if you do. It shows up about a week (maybe 6-12 days?) after conception. I had it for a couple of days myself, and started noticing minor pregnancy symptoms right after that. You won't get a a positive test until after implantation, but might get one pretty soon afterwards.
