Whats wrong with my body ??

Vanessa
Hey ladies so I missed my period on September the whole month and got it twice the next month of October and I asked my doctor to see if it was normal she said it was but to be honest  that I has never and I mean never happened to me and It gets me really mad that my doctor just says that's normal when I clearly know that it's not because That has never happened to me and my doctor did all the tests u could do and everything came out good so im just thinking why cant i get pregnant could it be possible thay it may be my BF with the problem??
