Yes, and I would count yourself lucky if you are one of those that don't get sick. If you have a positive test, then you know you're pregnant, and praise whoever you feel appropriate if you don't get morning sickness! :)
yes,you still COULD be pregnant. Not every woman has the same symptoms but nausea and tiredness are most definitely symptoms.
You can experience PMS symptoms and be pregnant yes. But if you get your period then you aren't pregnant.
Even in the presence of bleeding, you could still be pregnant.
YES.
Ofcourse. Not all pregnant women get nausea, just most of them. Brand yourself lucky.
If you really had a miscarriage, you can't still be pregnant, but you could be pregnant again before you get your next period.
yes. Yup!
yes symptoms vary from person to person
no Not unless he does it again and his timing is better.
No, you can have the symptoms and not be pregnant and not have any symptoms but still be pregnant. The only way to be sure is to take a test.
A woman cannot conceive while she is pregnant, but if the symptoms of pregnancy are false and she is not pregnant, she could conceive.
Yes, you could be testing too soon.
