How can she force you she's got no control over it lol she should be happy it's healthy! Deep down I wanted a girl, was convinced it was a boy and it turned out to be a girl! :)
I wanted a second boy and I knew when I went to the scan it was going to be a girl I just had a feeling and when the sonographer told me it was I girl I couldn't help but feel gutted but happy she was healthy. But a few days after it sank in I was happy and still am extremely happy to have one of each. Like I said once I was over not getting what I expected I was glad to get what I'm given lol x
Your mother in law sounds horrible! I'm so sorry for what you're going through. I really suggest you try and not to stress about that since pregnancy is already hard enough. I mean to me a healthy baby should be everyone's main concern not the gender. Ignore as much as you can and focus on baby and you. Good luck
