how do birthcontrol pills work?

Question

lets say i had sex with my girl today and didnt use protection when should she start taking the pills and should she stop taking them??

Answer 1

If she had unprotected sex with you, she needs to get to a pharmacy and get emergency contraception. This will cost about $40, and is about 89% effective at preventing unwanted pregnancy if taken within 72 hours of the unprotected intercourse. She should take the first pill of the EC as soon as she can, and take the other doses according to the pharmacist's and the packaging's instructions.

If you're talking about getting her on a hormonal birth control, she should start taking them for about a MONTH before she starts having sex again. If you must have sex until then, use a back-up method. Absolutely never have unprotected sex. Shame on you for possibly impregnating her.

Answer 2

Birth control pills are meant to be taken continuously BEFORE sexual activity. They work by combining estrogen and progesteron, two hormones present in females. The estrogen calms down the uterian lining and makes it harder for an egg to implant there. The progesteron stops ovulation. By stopping ovulation, an egg isn't released every month thus there is no way for the sperm to fertilize the egg and become pregnant. Birth control pills are meant to be taken at the same time every day. If even a few hours late, breakthrough ovulation can occur and the female can become pregnant because an egg was released. If your girlfriend decides to start taking birth control, she must speak with her physician and obtain a prescription. There is such a thing as the morning after pill, which would be used in your situation. It's to be taken no more than 72 hrs after sexual intercourse. The sooner the better. It's nothing more than high doses of estrogen and progesteron that will prevent the fertilized egg from implanting to the uterus. In some states, she will need a prescription for it, but in others, you can buy it over the counter at the drug store.

Answer 3

That's not how they work. She has to time the pills with her cycle. She can either start on the first day of her period or the frist Sunday after her period starts. If she starts the birth control pill on the first day of her period then no back-up method is needed (according to the package, but I would still personally use a back-up barrier method for the first pill pack, so 28 days). If she starts on the Sunday after her period then you HAVE to use a back-up method for 7 days (again, according to the package, but again I'd personally use back-up for the whole pill pack). She has to keep taking it, one pill every single day at the exact same time each day in order for it to work AT ALL. When one pack is empty she starts a new pack of 28 pills the VERY NEXT DAY. You don't just take them when you have sex. That doesn't work. So, if you already had sex and she wasn't on birth control, then she needs to take emergency contraceptive (the "morning after" pill) within 72 hours. But this is NOT meant to be used as regular birth control!! It is called "emergency" contraceptive for a reason! Regular monthly birth control works by supplying a regular does of hormones to trick the body ito thinking it's already pregnant, thereby preventing ovulation. Even then it's not 100% effective. I try not to be mean, but honeslty, will the uninformed and just plain stupid PLEASE STOP HAVING SEX?!

Answer 4

The pill needs to be at a steady constant level in the woman's body in order to prevent ovulation -- which is how the pill works. The pill needs to be taken daily in order to accomplish this.

If she has not been using the pill consistently (i.e., taking it daily for at least the past 7 days prior to unprotected sex), then the chance of pregnancy is HIGH. BCPs should NOT be stopped unless advised by the doctor.

If your GF has NOT been using the pill correctly, then she MUST be seen by a doctor or at Family Planning; pregnancy is likely.

Answer 5

You had unprotected sex? IT won't work by taking pills AFTER you've had sex unless you take the morning after pill.

And, pills are 99% effective, she should start taking them and don't stop until she doesn't mind having unprotected sex. Starting pills take about a week or two to be 'fully' (99%) effective against pregnancy.

You should be using a condom anyways with the STD's about.

Answer 6

Protection is not just for pregnancy is also for diseases, so you guys hold be more carefully, that how I got pregnant at 16 just one time without protection , but any ways, if she's pregnant is to late and she should be taking the pill before she has sex with you, the pill is to be taken for 28 days straight with a pause for the period and then you star all over again, please really think about the consequences

Answer 7

I would say she needs to visit planned parenthood and get the emergency contraception
