Yes. I would suggest taking another hpt!
A positive response is when a response happens to a stimuli, and this response causes more of the stimuli to happen. A negative response is when a response happens because of a stimuli, and the response stops the continuation of the stimuli.
Not necessarily. There are several steps between ovulation and pregnancy, and any of them can fail.
No there is no chance of pregnancy when you kiss. Kiss does not let the semen exchange between male and female. A proper sexual intercourse is needed to get pregnant.
Pregnancy normally lasts between 21-25 days.
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.
No! It is not possible to get pregnant by kissing.
Better yet, why are you taking that many pregnancy tests? I see two scenarios, the most obvious would be that you're newly pregnant and you've urinated all of of your stored HCG protein away, because you've must have drank a lot to make 6 pregnancy tests... Yes, you're pregnant. Stop taking tests as you're dehydrating yourself and your baby. Or, if there was a bit of time between these tests (not same day or within 3 days), you could have had a chemical pregnancy. A chemical pregnancy is a miscarriage. It occurs to 1/3 of fertilized blastocysts. After about 3-5 days of being "unpregnant" your levels return to normal=negative pregnancy test.
If you are 3 weeks late a pregnancy test, it will be accurate. Have you considered you maybe going through "the change" - menopause usually begins between the ages of 45 and 55. If your pregnancy test is negative continue to use birth control until you have missed 12 periods in a row - to prevent an unwanted pregnancy.
Between 37 and 42 weeks a typical pregnancy is 38 weeks.
Getting pregnant (Having a baby) when your a teenager. When you are a specific age like between 13 - 19 because that is when you are a teenager, when you are not a mature age and don't make the right decisions
You could be! When I was pregnant, those were some of my first symptoms; along with being extra tired and more frequent trips to the bathroom. My stomach never felt "weird" but I did have some implantation cramping. Take a pregnancy test, I like the "First Response" brand. You also could just be ovulating or about to get your period. Because of the Progesorone produced between ovulation and your period, it is possible to have pregnancy like symptoms. Home pregnancy tests are best taken in the morning when you first get up and the day after you expected your period. If you are pregnant, enjoy it! :)
It depends on the test you are talking about and the time you had the test taken. It is possible to still be pregnant if you have gotten a negative home pregnancy test. Normally it takes between 12-19 days for implantation to take place. 2 days after the implantation the HCG levels with be present in your urine and then you will be able to see a positive result. It appears sooner in your blood so a blood test can detect pregnancy sooner. However , though it is rare, there are some women who are pregnant and the HCG levels don't show up in their blood till they are sometimes 3 or more months along. If you think you are pregnant and have all the symptoms but keep getting a negative result, I would suggest getting an ultra-sound... if they see a fetus you are pregnant. Hope this helps :) Been there and didn't test positive till late into my pregnancy.
