Protected sex and plan b. Recently taken many plan b. Lots of neg pregs tests. Am i pregnant or is Plan B making my period irregular?

Irregular periods: Low risk of pregnancy. Irregular periods/spotting), headache/fatigue/nausea/ abdominal pain are common side effects with plan b. Plan b should not be used as routine contraception, please see your doctor/discuss what birth control would be right for you. Report any lower abdominal pain. Practice safe sex (use condoms) as birth control does not protect from sexually transmitted diseases.Take care. ...Read more

If she took Plan B friday and had sex sunday will Plan B one step still work?

If she took Plan B friday and had sex sunday will  Plan B one step still work?

Perhaps not: Plan b causes a spontaneous abortion, by causing the lining of the uterus to shed the implanted and fertilized egg. So the protection for unprotected sex, after the fact is not assured. Please, if pregnancy is not the desired outcome of sexual intercourse, use other forms of contraception. Plan b is not intended to be a form of birth control and should only be reserved for emergency situations. ...Read more

Does Plan B still work before unprotected sex?

Does Plan B still work before unprotected sex?

Depends: If you took it and shortly thereafter had unprotected sex it would likely work the same way. However, i wouldn't suggest planning unprotected sex.

I had unprotected sex on ovulation day with withdrawal. Took plan b after 12 hours. Will plan b still work?

Try Ulipristal/Ella: Unfortunately the primary mechanism of Plan B is the prevention of ovulation, but if the cat's already out of the bag, meaning you've already ovulated, then there might not be very much that Plan B can do. You may however call your doctor and ask for a script for Ulipristal or EllaOne which is more effective than Plan B and safe for the prevention of pregnancy at up to 120 hours. Good luck! ...Read more

Does Plan B work if taken before unprotected sex?

Bad idea: Plan B works by blocking ovulation; once it wears off ovulation continues. If you have sex, the sperm sticks around, and once the pill wears off, the egg will come into contact with them once released (you actually increase your chances of getting pregnant). To really prevent pregnancy, best to use condoms and a second method such as BC pills every single time (why take a chance?) ...Read more

Can the Plan B pill be effective four days after unprotected sex?

Can the Plan B pill be effective four days after unprotected sex?

Don't expect: strong protection after 72 hours. Plan B One-Step is up to 89 % effective when taken within 72 hours (3 days) after unprotected sex. It can reduce chance of pregnancy by up to 95% if used within 24 hours. It continues to reduce the risk of pregnancy up to 120 hours (5 days) after unprotected sex, but is less effective as time passes. ...Read more

Will Plan B work during ovulation? Ejaculated inside without condom and took plan b 6 hours after.

Will Plan B work during ovulation? Ejaculated inside without condom and took plan b 6 hours after.

Effective: Plan B consists of hormones, which, given early after unprotected intercourse, "mess" with the mechanisms that are needed for successful conception and/or implantation of a fertilized egg. Under ideal circumstances, conception rate is only about 25 % to begin with. The only way to be sure that Plan B was effective is to do a urine pregnancy test the earliest a week after the unprotected IC. ...Read more

I had unprotected sex with my gf and she took Plan B. About an hour after taking the pill, we had sex again. Would the Plan B still be effective?

Plan B: Plan b essentially disrupts the normal menstrual cycle by blocking or delaying ovulation. That it is how it works and why it is so different than a medical abortion. Irregular bleeding after taking Plan B is not rare. Always check a pregnancy test after using Plan B and see a doctor to start a better form of birth control. ...Read more

I took plan b on day 3 then my partner ejaculated in me 2hrs later is the plan b still effective?

Could be as the: hormone levels in your body are still high. The odds of you conceiving with such hormonal levels from the Plan B are close to 0. But I would still be careful and not use plan B as a contraceptive. Best if you use alternate more reliable methods such as oral contraceptive, implants or IUDs. Thanks for trusting in HealthTap. ...Read more

Here are some ...: Nowadays, how to handle the uncertainty of pregnancy has changed through the readily available HPT, which has taken away the anxious second guess with clinical suspicion of morning sickness. So, do HPT soon after missing the regularly expected period and repeat it in 1 wk if the 1st test is (-) & still in doubt. Besides, note: no known contraceptive measures have ever offered 100% success. ...Read more
