Maybe a month or a few weeks.
2 weeks
it takes a girl until after a missed period and a hpt or a trip to the docter before she knows she is pregnant .. but a missed period is definetely a huge sign .
one month or two will suffice
It's impossible to know based on that. To know how long she is pregnant, she really should see a doctor... which she should be doing on a regular basis anyway if she suspects or knows that she is pregnant.
3 months
Well you go to the doctors office and then you have to do a sonogram and then if you ready have been pregnant long enough they can probably tell if it is a boy or a girl.
A person can now find out if they are pregnant before even a period is missed.
7 weeks! 7 weeks!
With in 12-24 hours your body knows its pregnant. But you wont know for about 3 weeks.
I want to know how long can be pregnant?
Yes. As long as there is sperm pregnancy is possible.
9 months
