Threaten Miscarriage...

Yesi β€’ I'm a mommy to a wonderful soon to be 9 year old. I'm currently pregnant w my 2 child.. I have an amazing step daughter & a wonderful hubby.. πŸ‘¦πŸ‘§πŸ‘©πŸ‘¨
So today I'm 9 weeks.. I woke up at 5 am to use the bathroom & when I wiped I was spotting then when I look in the toilet there was a small blood clot floating down.. remind you i have a very small Subchorionic Hemorrhage.. went to ER to make sure my little peanut was ok.. sure enough they did an ultrasound & peanut was good heart rate was just a little high 181 but dr said baby is ok.. when I get discharged I was reviewing my discharge paper & i see i was diagnosed with Threaten Miscarriage.. had anyone been diagnosis or have heard of being diagnosis with Threaten Miscarriage..
