yes, antibiotics can cause BC pills to fail. that is why you always have a back up form of BC such as a condom.
You probably just worried. It doesn't show that fast if you are pregnant. well, your supposed to get pregnant during your period (if unprotected sex)and it does stop when that happens..... mabye you should get a test
It is certainly possible for you to be pregnant as there is no "safe" time in a month to have unprotected sex.
I had unprotected sex three times in a row and didn't change the patch when I was supposed to and also had unprotected sex after I was supposed to change the patch and didn't get pregnant. I was on it for 3 months at that time. The spotting will turn into you period, at least mine did. Good luck It is possible. If your period doesn't come take a test. Even if it is negative use contraception next month. Be more careful next time.
What antibiotics make you constipated
no
yeah.
There is always a great risk of getting pregnant when having sexual intercourse without a proper form of protection, especially if one does not follow instructions for their birth control pill.
She is supposed to be Nathan Kress's girlfriend
I don't know about supposed to be as much as you might mean it can be. If it's a new girlfriend or if there was a recent situation that makes things awkward, then it can be awkward.
no
If you miss your period then go get tested.
She's not pregnant so niether
