My first baby is now just eight months old.i had unprotected sex with my husband on the day of ovulation.what pill to take to avoid pregnancy?

Plan B: Plan B can be taken within 72 hours of intercourse. A better strategy if you do not wish to be pregnant yet is to get on some form of contraception.

Plan B: Plan B is an over-the-counter emergency contraceptive available in the United States to anyone over the age of 18. This will delay ovulation and hopefully prevent the sperm from meeting the egg. The pill contains levonorgestrel, but no estrogen, so it should be completely safe while breast-feeding. There is also a prescription pill called "ella" which works up to five days afterwards.
