Yes, most symptoms stop at the end of the first trimester
it is possible
no
If you are on/had your period your probably not pregnant, but do a pregnancy test to be sure.
It is possible to have a fake pregnancy, where you want so badly to be pregnant, that your body recreates all the symptoms of pregnancy.
Yes. The symptoms can be due to normal illnesses or to hormone fluctuation.
The first trimester is 0-12 weeks of pregnancy, roughly 3 months
Yes, it's possible, but it's pretty uncommon. Most likely if you have no symptoms you're probably not pregnant. And if you are pregnant, but don't have any symptoms, you might just not be noticing them. But it is possible to be pregnant and not have any symptoms in the beginning. With my first pregnancy, I didn't know I was pregnant until I was talking with a friend and brought up something about period schedules and she is the one who told me I was late. Then looking back, I realized I had some symptoms, I was just busy and didn't expect to be pregnant, so I didn't really notice anything. But I was less than a week late, I would have realized it in a few more days.
If you're not taking the pill, it's always possible to get pregnant, fake symptoms or not.
It is possible to be pregnant if you are still having your period. Its not unheard of for women not to notice until they are well into the pregnancy.
Always possible but it's normal for some girls to have irregular periods.
Not a lot of women are pregnant and experience no pregnancy symptoms. But I would say about 2 months into the pregnancy and beyond they should experience pregnancy symptoms and a LOT of women experience symptoms a few days after conception.
There is a very slight chance. With pregnancy, there are always exceptions to everything.
