I’m new pregnant! So of course I have a few questions/concerns

I have a 6month old lab puppy and I live in apartments. I have to take him out every morning to do his business. He often yanks my arm a lot and kinda jerks me around. I just really want to know if any of that can possibly cause a miscarriage?

I often get pretty stressed about about nothing and I know stress is bad. What are some ways that can help me destress and relax?

When getting ready for bed I’m already so uncomfortable trying to get in the right spot that doesn’t hurt. Im not sure if that’s normal for only being 6 weeks? What’s a trick to get comfy?

Any advise is greatly appreciated! XXX ❤️
