Sort of 2 questions in one, sorry. my friends super worried cause her hormone levels but cant be tested yet?

I'm sorry but I gave up on reading all that. If she wants to put her mind at ease they can do a l ultrasound to check for a heartbeat. Its the same machine and everything but instead of the rectangle thing they use like a long skinny thing to stick in and check the baby and other stuff. It doesn't hurt or anything.
