You don't. The only way to know for sure is to take a home pregnancy test or see a Dr.
You would know if you're pregnant by taking a pregnancy test. A pregnancy test can be taken from two weeks after intercourse and doesn't require you to know when your period should have started.
You might not be pregnant, you know. Sometimes it's regular for your periods to be irregular.
yes, its possible that you can be if your periods has always been irregular they often still longer if you but that's how you know.
You do not know as it is irregular.
Uh, yeah.... some women are irregular. I know of some women that don't have their period but every 4-5 months.
You can. It makes it harder to become pregnant since the cycles are so off balance. But, it is indeed possible. Some women bleed throughout their entire pregnancy and go off to deliever a healthy baby.
It means that your periods may be slihtly irregular, it is very common for this to happen. Otherwise, you might be pregnant, but i think you will know if you are :L
has your period come yet? if it has your not pregnant if it hasn't then you are (but take a test just to be sure)
You will know if you are pregnant if you miss your period.
If you have period you are not pregnant.
If a girl has her period it all she is not pregnant. Irregularities in when the girl starts her period are a natural phenomena. the only way to control is, is by using the anticonception pill, but "the girl" has to see her doctor about that.
There is not for sure way to tell that you are pregnant without a test, especially if you suspect that you are pregnant. Look for symptoms such as swollen/tender breasts, nausea, missed period, and fatigue/tiredness.
