Control
Planned Parenthood post comparing forms of birth control.
- An implant is the most effective (99%) method to prevent pregnancy and to mitigate menses problems (such as cramping) without estrogen (a hormone). It lasts 5 years.
- A shot is 96% effective and has to be renewed every three months.
- An IUD is also 99% effective and lasts up to twelve years but uses hormones to mitigate menses problems. The first day after insertion can be uncomfortable – similar to the cramping of a very heavy menses.
After Intercourse
Planned Parenthood post differentiating Plan B from the abortion pill. It can take up to five days after unprotected intercourse for the sperm and egg to connect. During that period, an emergency contraception pill (Plan B) can be taken to stop ovulation (and to thus prevent pregnancy). If ovulation occurs in the presence of viable sperm, then medication abortion can be used to halt the progression of the pregnancy and to then empty the uterus.
