SIL is bleeding at 11 weeks

So I am 6 weeks and 5 days pregnant. My sister in law is almost 11 weeks. I had a nightmare last night that I was bleeding and woke up to a phone call that my SIL actually IS bleeding now and is on ordered bed rest. I am heartbroken for her. Pregnancy can be so scary. They got pregnant via <a href="https://glowing.com/glow-fertility-program">IVF</a> and this may be their last shot. Does she have any hope? Please pray. They had just done their second ultrasound recently too and all was well. :(  what are everyone's thoughts? Anyone been through this? I am so scared of miscarrying my own and seeing her go through this terrifies me.
