My friend is saying that she is pregnant. First of all she says that she hasn't gotton her period. She has taken three pregrancy test all blood test and it has all come back negative. Two nights ago she went to the ER because she was having a lot of pain. While there they did an ultrasound and they told her that the ultrsound looks like she is about 3 weeks pregnant. And then she say that the reason that the blood results are coming up negative due to the medication she is taking. I don't know if she is telling the truth or not. I thinki that she is lying so that she can get her ex back. First a blood results won't come up negative and an ultrasound i don't think will tell you your 3 weeks pregnant I think she is lying. What you think?
