Girls, is it true that taking Utrozhestan until the end of pregnancy means they can't have children themselves?? I read and now I'm panicking. I've been on Utrozhestan since week 4 and my doctor said I would be until the end of pregnancy. But there are no indications, why doesn't she cancel it - I don't know, she says it makes her more comfortable. But today I learned that you can't give birth yourself afterwards. And I'm set on having a baby.
