I'm currently 15 weeks 2 days and last week I did hear the baby's heartbeat twice, both times I was told the baby is super healthy and I was too. But the past 5 days or so, I've been really stressed and crying a lot. Will this cause a miscarriage or should the baby still be okay? I know I might be paranoid, but I've stress can. This is my first pregnancy, and I just want to make sure I take care of my little one.
