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 IVF 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.
