A woman shows signs of being pregnant when she first misses her periods or when the periods are delayed.
While it is rare, some women do continue to have periods (I know a couple). Most likely is is heavy spotting due to being pregnant. That is much more common.
I know about the pill. I have know women (not many) that have gotten pregnant while on the pill, but as soon as they got pregnant they no longer had any periods. I hope that this helps:)
There are a few medical reasons for women to get bloated stomachs while not being pregnant. Gas, accumulation of residue, hysterical pregnancy...
They missed their periods.
If she never has periods and never ovulates, then no, she cannot get pregnant.
If a women is pregnant than she will miss all of her periods, until she gives birth. then she will have a period every 28 days like normal
Usually but not necessarily. Some women can have one or two periods after they become pregnant but it is somewhat rare. The best way to see if you are pregnant is to get a test.
It is very well possible. Many women have had actuall periods while pregnant. No two women bodys are alike.
not technically, but she can still experience vaginal bleeding
Some women say they are sore, other women experience soreness with periods.
If you have had sex before you had any periods, no. You're not producing egg cells yet, so you're not yet fertile. If you mean 'can you be pregnant while not having periods', yes, when pregnant women don't have their period. A period is the discarding of unfertilized eggs, which you don't do if you have a fertilized one growing in your womb.
