Is she or isn't she?

I dnt mean to come bad as insensitive but my girlfriend claims she went to the doctor today and found out she's pregnant. The function she went is that she be peeing a LOT so we assumed she had a bladder infection. I did some research and it say it IS a symptom but not until later on...have anyone ever had frequent urination as their FIRST symptom. I'm sure i'd awareness if she has any other symptoms. I dnt wanna confront her roughly speaking it so is it possible she's telling the truth or is it simply another mind game women approaching to play? She could be.
I went to my doctor because I thought I have a bladder
infection (peeing alot)
I was PREGNANT
I be 6 weeks along
my first symptom was heartburn (which I thought wasa sore throat because I'd never have it before) and frequent urination. the bigger question is why don't you trust your friend??
