I imagine after trying for a year to get pregnant and it not happening that you figured it was not possible.
I would say that if you want to know now go to the Doc's office and ask them to do the ultra sound now. Either way you'll know.
I tried to get pregnant the first year hubby and I were married. No luck. I took temps, charted, did everything and since my first pregnancy, with my ex, had happened right away I accepted my new hubby and I would not have kids together.
I've not taken any form of birth control in the 22 years we've been married.
Still not pregnant. When it keeps coming up not pregnant over and over and over and you're having sex like bunnies you come to accept you can't get pregnant.
So stop being mean to her. If you've ever accepted something like that it just is what it is.
I would imagine your doc should go ahead and do the ultra sound. It's not fair to make you wait for no good reason. Either you're pregnant or you're starting menopause. There are other options but not good ones.
