emergency contraception
"I took it 1 hr after unprotected sex. First days no symptoms. Then I had stomach pains for about 5 days. After they went away I would wake up feeling weak and felt like throwing up when eating breakfast. After the morning I was fine all day. This all lasted for 2 weeks and period came 4 days before it was due! Thank you plan B so much. I was so stressed and scared, birth control will start asap!"
