i'm only a teen, is my ex pregnant?

Usually I like to give advice right now all I need is advice. This girl that I was going out with I had sex with her 3 months ago and a wk after we had sex she broke up with me. Now shes telling me she took a pregnancy test it came out negative but she's been missing her period since May. Shes also been throwin up here and there but I just want to know other ways to find out if she is pregnant. Please I just want to be a man about this and not crew it up.

she needs to go to the doctors and get a test done professionally.

that is the only way she will know for sure.

Yea, she needs to take a blood test at the doctor's office.

Good Luck
