A placebo has no medical properties at all so, yes, you would be at risk of getting pregnant.
No, the placebo pills are exactly that, placebo. (just sugar pills). It would be like expecting a tic tac to bring on your menstrual cycle. If you are on the pill, the placebo pills will start your cycle because they have no active ingredients. If you think you are pregnant and want your period to come, go to a doctor/do a pregnancy test or take the morning after pill if it's not too late.
menstrual hygiene
Your period usually comes during the placebo pills week(sugar pills).
you will get your period when you start taking your "period" placebo pills in your pack
There is always a slim chance while on the pill you might get pregnant. However if you have been on the pill for at least a month and have not missed taking it you are probably not pregnant.
The purpose of taking placebo is so that a person can think that they are doing the real thing. This is a pill.
If you've been on birth control for over 4 weeks then you're protected against pregnancy.
no
NO probably not
It would depend how long you have been on the pill before. If you have taken the pill for over 7 days then you are protected while you take the 'period gap'. If you have only just started taking the pill the chances are low but you still could become pregnant.
If you had sex it is possible you are pregnant. The chance of getting pregnant on your period, while taking BCP is quite small.
By skipping the placebo week, you only lower the risk of accidental pregnancy. It's possible to get pregnant using the birth control pill, but taking the packs back to back doesn't increase the risk.
