How to tell if she's lying

Ok. I had slept with this girl about a month ago, the condom completely broke. So obviously there is a chance she is... However, this girl also has been trying to get me to be with her forever. She is saying that she has been sick and she threw up...

once in the morning. She has a lump on her boob and she says they hurt. I know these are all the signs, but the problem is, is that I've never seen her sick, throw up, or anything. She doesn't eat, she's never hungary. And she wants me to give her money to get an abortion. She is also a week late. Can anyone here give me some advice on other things to look for when you first become pregnant because something just feels off about the whole situation???

I think shes using you,
you should talk to her
Good Luck!

these are a couple signs :

missed menstrual period
nausea
extreme fatigue
frequent urination
tender breasts
headache
heartburn
constipation
spotting
feeling faint

if you feel like she's lieing to you. take her to the doctor yourself and have her get a blood test that is a definate way to tell if she is or not.

Its way too early to be having symptoms already. Being she is a week late, buy a pregnancy test, and have her do it with you there.

IT'S WAY TO EARLY FOR HER TO BE HAVING ANY PREGNANCY SYMPTOMS. I THINK SHE IS JUST TRYING TO GET MONEY OUT OF YOU. I WOULD MAKE HER TAKE A PREGNACY TEST IN FRONT OF YOU. DON'T LET HER WALK OFF WITH IT AT ALL...SHE MIGHT SWITCH THEM. GOOD LUCK TO YOU

Hey thanks to you all, I'd probably be really nieeve if I wouldn't have all your support. Thanks again!

Tell her you want to be supportive and go with her to the clinic. If she is telling the truth, it would be a really stand up thing to do. If she is lying, she will find some way to back out of it... like a surprise miscarraige.

for like the first 2 months a lot of people don't even know their prego, because you don't show any signs yet., so I think she is using you.

I knew very early on. I could tell by my hormones on week 2 or 3. Maybe I'm an exception.

for me before its 3-4 weeks before it showed symptoms..and in addition to symptoms, her eyes will always look tired and all she want to do is do nothing..I think shes jut using you...good luk

Update to all of those who gave wonderful advice... I recieved a phone this call this morning after yesterday taking all your advice and telling her I'd go with her to her app. and this morning she had a mysterious miscarraige. Thanks for all your help!!!
