If you want to lower your chances of having a child. Nothing is one hundred percent yet. It is suggested you use both. Otherwise you or your partner have a greater risk of becoming pregnant. But no you do not Need to use them. It entirely depends on whether or not you want a child.
According to Cambridge University Press, they all express necessity and are similar in meaning, thus interchangeable. In colloquial speaking they are more or less used in the same way. According to Oxford, "need" is the personal opinion of what is necessary, "have to" expresses a general obligation outside the control of the speaker, as in a law or rule, and "need to" is used in both contexts. However, I have read in many places that need and have to are not officially modals since they change in tense and add third person -s. I am more likely to agree with the Cambridge source, personally.
need form
You need to solve the equation:log3(x-1) = 0 Taking antilogarithms (base 3) on both sides, you get: 3^log3(x-1) = 3^0 x-1 = 1 x = 2
This is the internet age. Take advantage of it! You don't need to play any of these guessing games. There is a site called zfinger.com. You create a secret list of who you like. They create their list. If there's a match (you like eachother), the website notifies both of you. If not, nobody ever knows. Its quick, easy and free.
you need two equations to answer it, or you need to know the value of x.
Absolutely YES! Birth control pills only protect you from getting pregnant. Condoms, while not foolproof, will protect you from STDs.
Well, I am not sure what you need help with. Generally switching birth control pills isn't a problem. You do need to wear a condom until she finishes her first complete pack (or month's worth) of the new kind of birth control pills before you have sex without a condom.
Yes. But only if the condom broke or was expired. You should also be on some kind of birth control pills. I reccomend Yaz . With both, pregnancy is at such a low rate you have no need to worry.
Birth control is 99.9% effective when taken properly, so you do not need a condom to protect yourself from pregnancy. However, if you are not in a monogamous relationship; meaning, if you have more than one intimate partner, you should use condoms to protect yourself from STI/STD's.
Wearing a condom when she is on the pill will help prevent the transmission of sexual disease and lower the chance of conception. The pill does not prevent STD's. No form of birth control is 100% effective except for abstinence.
better to use one now than wish 3 mos from now that you had
No it will not. However it may help prevent urinary tract infections. If you don't want sperm in there you need to use a condom or some other form of birth control. pulling out, douching, urinating after sex, wearing a jar of gypsy tears around your neck are NOT birth control. Condoms and birth control pills are both very effective if used properly.
Because you took your non active pills instead of the active pills this has basically interfered with birth control protecting you against pregnancy and has also messed up your cycle. You must ALWAYS take birth control as prescribed. You need to use a condom for the next 4 weeks to prevent pregnancy and take your birth control as normal.
You will not be protected against pregnancy and your period may arrive late. You need to use a condom for 2 weeks.
YES. If you dont take your pill by like 3 hours after your usual time, you need to get a back up birth control(like a condom). If you have unprotected sex, then consider the morning after pill or Plan B.
Condoms are 99% effective but all it takes is that 1% or it breaks and you're pregnant! The best combination is condoms and birth control pills.
BCP do not protect against STI's or HIV. If you and your partner are sexually monogamous with a prior clean slate for STD's you do not need a condom. Many woman use a condom just to prevent that tiny little chance of pregnancy, the pill is 99.5% effective when used as directed. Using a condom gives piece of mind if there is ever a forgotten BCP. What you don't need to use while on BCP is Emergency Contraceptives for condom breakage etc. The OCP at 99.5% protection is well over the protection one would get from the ECP.
