Saddened miscarriage

My friend just posted a status this morning about how she had lost her baby. She didn't say when I'm not going to be that annoying person to ask when and all the details. But now I just feel horrible since she was as far along as I am and awhile back I had asked if the product line she sells has stuff for stretch marks. So now I'm just worried that I asked during that time it happened and how do I go on continuing to be happy and sharing my journey knowing she won't be doing the same? I'll just feel like a horrible person.
