Yes, of course if you were to get pregnant you'd not menstruate. Menstruation only occurs when you don't get pregnant.
You can get pregnant a week before your period, the week of your period, and the week after your period, and some pregnancy tests are faulty.
It varies by person. But I've done this before and you will probably just have a really light period (i.e. spotting).
depeding on the brand of pregnancy tests, you can take them up to 5 days BEFORE you miss your period. You can take one as soon as you miss your period. However, the longer you wait after you miss, the more accurate the test will be.
2-4 weeks
one week
No you cant its very unusaul to miss a period ok no need to ba alarmed
i dont know maybe a week or 2
don't take it off, just carry on without the week off (week 4) till next time you should do it. It will mean you will wear 7 patches before taking it off. You will miss your period but after that it should be back to normal.
It is fine to swim during your menstrual cycle as well as before or after it.
If you have a period than you are not pregnant
mine was a week before my period my friends was a week after her missed period..
Usually you get PMS symptoms about a week before your period is due to start.
