Like mentioned before I've been on Trinessa for many months, and a couple weeks ago I had unprotected sex, used the pull out method even though we are both aware that's not safe either. I started my period the very next day. Is there anyway I could be pregnant? I'm pretty sure I'm overreacting and scaring myself, but I'm just worried and wondering,
You are on the pill, there is no better birth control. You are more then 99% protected. Then you're having your period. You don't do that when you're pregnant.
You don't need any other birth control when you're on the pill if you are taking it correctly and aren't on antibiotics. You're not pregnant.
#1. You are on the Pill which is 99.9% effective when taken correctly #2. You had your period. Usually a period signals that you are not pregnant especially a full normal period. So I'd say chances are extremely slim that you'd be pregnant. Trinessa and other oral contraceptives (birth control pills or "the Pill") stop ovulation. That is the main way they work. If there is no egg released, there can be no baby no matter how much sperm is present. You are right, the "pull out method" doesnt work on its own but when you are on the Pill, it is not necessary. Since you dont ovulate, he cant get you pregnant as long as you take your pills every day about the same time a day. The Pill is really all the protection against pregnancy you need. They often tell young girls to be sure to use condoms and I think this tends to confuse. Condoms need to be used for birth control the first seven days of the very first pack of pills (some Drs want you to use them the whole first month) only but after that, they are not necessary for contraception. They are for protecting you from STDs. If you are sure your partner is disease free and having sex with you only, then condoms are a choice. They are to prevent STDs-you dont need them to protect against pregnancy-that is the Pill's job-unless you miss a pill or you are taking antibiotics. Missing a pill, especially more than one in a cycle puts you at a higher risk for ovulating. The Pill stops and hormonal trigger that tell your ovaries to release an egg. Without this hormone, no egg is released so no pregnancy can occur but if you miss enough pills, an egg may be released so when you miss pills, it is best to either use condoms again until you have taken seven active pills or avoid sex until you take seven active pills. When you take antibiotics, they can reduce the effectiveness of the pill. In fact, some women have breakthrough bleeding when they are taking antibiotics. The body bleeds in response to the drop in certain hormones. When you take a week of placebo or reminder pills the 4th week (or if you are on a 21 day pack rather than a 28 day pack, you skip a week's pills) the level of hormones drops to trigger your bleeding. Antibiotics can reduce the effectiveness of the Pill which in turn drops the hormone levels and this leads to breakthrough bleeding. Anyway, it can also trigger ovulation so it is important to use condoms the whole time you are on antibiotics and for seven days after you finish them. Other than these two reasons for back up protection, condoms are not necessary while you are on the Pill and taking it correctly and there is also no reason for him to "pull out". You are safe and protected from pregnancy.
