No, some women know before however most home pregnancy tests will not show a positive result until that time.
Before you start to bleed you ovulate so yes, you can get pregnant before you start to bleed. You will not know if you are in your period before you bleed.
You have to "do it" before you period so the eggs will be fertilized and and you will become pregnant. But, you don't do it before, you will have you period when the eggs are rotten and the eggs will be gone. And you will have to wait another month. I am only 8 and I know this.
A person can now find out if they are pregnant before even a period is missed.
You will know if you are pregnant if you miss your period.
You can miscarry before you even know your pregnant and just think it's a late period
If you have period you are not pregnant.
Take an early response test.
No. You do not have a period if you're pregnant. My mother had 6 children, and she had her periods through 3 of the pregnancies - I don't know how long or "normal" her periods were (she died some years ago) but I do know that she was 5 months pregnant with me before she realized she was pregnant!
I have before my period, I start my period for 3 days then My period was stop after my period for 3 days, I want to know what happened to me?
About 9 days after conception if you know when you concieved. Otherwise about 6 days before your anticipated period. Levels of HCG will be present and a blood test will be able to tell you if you're pregnant or not.
It is rare, but you can be pregnant and still get your period.
Just because you skip your period, doesn't mean you are pregnant.
