i didn't ejaculate at all, and withdrew only after maybe 20 seconds. and we didn't use any protection. i just realized that i didn't want to do it, and neither did my partner. but we're still worried that she could get pregnent. about 2 hours later, maybe slightly less, she took an emergency contraceptive pill, the Plan B one. she took one then, and then took the second pill 12 hours later like she was supposed to. her "bleeding" was due to come about a day after the incident. could she still get pregnent?
