Do pregnancy tests work after 12 weeks?

Can I be 2 months pregnant and have a negative test?
The hook effect incorrectly gives you a negative result on a pregnancy test. This can happen during early pregnancy or in rare cases — even into the third trimester, when it’s pretty clear you’re preggers. During pregnancy your body makes a hormone called human chorionic gonadotrophin (hCG).
Can a pregnancy test be negative at 2 months?
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 anything interfere with a pregnancy test?

Can I be 3 weeks pregnant and still get a negative test?
Even if you did miss your period but it hasn’t been at least a couple of weeks since you conceived, you could still get a “false negative.” That’s because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.
