Can pregnancy tests not work??

Question

OK so, i took two tests...both came back negative but i missed my period, i'm nausous, and i have headaches like no other....can they not work on some people?

Answer 1

It is a possibility for a pregnancy test to be wrong, but it's rare. If anything, make an appointment and get a blood test done (they are more accurate) Otherwise, try again later a couple days later, and see if there is any change.

Answer 2

Can I still be pregnant if the test is negative (have a "false negative")? In a word, yes. You could be testing too early (before your baby is making enough pregnancy hormone to be detected by the test.) And some women (this is fairly rare, but possible) never get a positive urine test even when they're definitely pregnant (for some reason the hormone doesn't make it into their urine.) I have a friend who didn't get a positive HPT until 25 DPO! (With her second baby, a test at 23 DPO was negative . . . but a test on 30 DPO was positive. Oddly enough, with #3, her positive test came at only 12 DPO.) If you get a negative test but think you might be preggo anyway, wait a couple of days (giving the hCG hormone time to build up) and try again. It's not over until the fat lady sings-- and your period crashes the party.

If you are not monitoring your fertility in any way (OPK's, charting cervical mucus or basal temperature, ultrasounds) it becomes extra-tricky. There are two parts to every menstrual cycle: from the start of your period to ovulation, which can vary quite a bit in length, and from ovulation to your next period, which is usually consistent in length. (This second half is known as the "luteal phase," and the normal range is 10-16 days. It's normal for your typical luteal phase to vary by a day or two. For example, mine is normally 11 days, but 10 and 12 are not unheard of either. I have also had a couple of longer ones by total fluke.)

Because ovulation can happen at any time, it's possible your egg was delayed for some reason (stress, illness, travel, excitement.) This doesn't mean your period is actually "late" (it could arrive within the normal 10-16 days after ovulation), but rather than your entire cycle was delayed due to a later-than-usual ovulation.


Maybe you took the test too early for it to show up. Have you missed your period yet? Go and have a blood test done. A blood test will show you are pregnant 6 days after conception. (100% accurate)
Good Luck

Answer 3

It is absolutely 100% possible.. It may be extremely rare, but it happened to me FIVE times with the standard EPTs. I was already having morning sickness and many other fairly obvious symptoms of pregnancy so I was at least a month or two into the pregnancy. I kept taking them out of paranoia because I'd never been pregnant before and I thought they with such alleged accuracy couldn't possibly be wrong 5 times so I assumed I had some horrible unknown physical ailment of doom until I tried again a 6th time to prove I wasn't pregnant and THEN it gave a positive sign, we went to the docter and yep.. I totally was... Took until the 2nd trimester for me to know.

Make sure to get a good clear test also.. Get an EPT digital so the given answer is unmistable.

Answer 4

Its very possible!!! I have a few friends that never had a postive home pregnancy test, but was positive at the doctor's office. Go in and have a blood test done.B/c if you arent pg, there could be something else going on.

Answer 5

Go get checked by a doctor. You can have false negatives but rarely false positives.

Answer 6

GO TO DR!! Maybe you are not very far along or had a bad batch of tests.....GO TO DR
