They are as good as if you had not been taking ecstasy. That is to say it depends on where you were in your menstrual cycle. You are also at risk for having caught any of several STD/STIs. It would be prudent to get an STD test as well as a pregnancy test.
Chances are Good. In fact you may already be pregnant, which is why you aren't having a period.
The pill is not as effective if you are not consistant with taking the pill. You have a chance of getting pregnant, but no one here can give you a percentage. It is best to continue taking the pill until you know for sure if you are pregnant.
Yes, unprotected sex can get you pregnant.
The same as every other woman who is not using birth control - about 30%.
Possibly, get a test and see. well there is most likely you will be pregnant if you had sex unprotected.
If you miss 1 or 2 days of taking your pill, there is a chance, albeit small, to get pregnant. You didnt specify when you had missed your pill in relation to when you had unprotected sex. If it was within a couple of days, chances are small, but you could become pregnant. If had unprotected sex several days(4 or 5) after missing a dosage(but immediately resumed normal dosing), you should be okay. Above all else, an HPT would be definitive.
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.
Yes
By having unprotected sex.
There are such chances but in a very little percent.
There is a 50% chance that you are pregnant if your fiancee and you had unprotected sex, you are not on birth control and he did not pull out. If this happened twice, it is 50% likely that you are pregnant but the only way you will know for sure is by taking a pregnancy test.
The chances are extremely low unless you have a pre-existing heart condition in which you should avoid taking ecstasy altogether.There have been cases of people dying during their first ecstasy trip but they are very,very uncommon
