Twin Gender Guesses

We just found out we are expecting twins and one heartbeat was 143 and the other was 150. Any guesses as to the genders?

My husband's mom was right when we had our 3 daughters. She had a dream with each single pregnancy I had with my daughters and she told me that she saw baby girls sure enough we have girls

She told me she had a dream that it is a boy so we are really hoping we have boys. I'm only 7 weeks 6 days

Thank you 🙂
