Hello, I took Plan B on November 9th, 2013 after a condom broke during sex. I took a pregnancy test (First Response AND Dollar Tree tests) I took one on Dec. 2nd and one again on Dec. 10th, so three weeks and about a month after said incident. All tested negative. Is this safe to say I am not pregnant? Sorry just this whole experience freaked me out so badly I keep thinking I am pregnant. Thanks for your help.
