Why is my belly line not straight?
No, there’s no need to worry if your linea nigra is not completely straight. It can look different from woman to woman. Linea nigras can be crooked, completely straight, or squiggly, and none of these are any cause for concern. It’s simply how the pigmentation has formed on your skin.

Why are my pregnancy test lines getting lighter?
The strength of the positive test line depends on how much hCG is in your urine. If the line is faint, it usually means that the hCG level is low. One reason why hCG levels may be low could be because you’re still very early into your pregnancy.
Has anyone had negative pregnancy test but still pregnant?
Is it possible to be pregnant and get a negative pregnancy test result? Yes, it is possible. Getting a negative result doesn’t mean you’re not pregnant, it may just mean your hCG levels are not high enough for the test to detect the hormone in your urine.
Can twins make pregnancy test negative?
This is called the ‘hook effect’. It’s more likely to occur in cases of twins or triplets, because the level of pregnancy hormone is so much higher. The hook effect in itself is pretty rare, but there are other reasons for producing a false negative. The most common reason for a false negative is testing too early.
