My sister and I are about 2 years apart. We are in our early 40's. She has never been married and has no kids. She's had a few live-in relationships. I found out accidentally yesterday that she may have been pregnant recently and lost the baby! She never said anything to me or our mom about this. I found out because she gave me a couple of magazines that she had read and in one was a sheet of papert that had some expenses listed and there was an entry for "$350 medical expenses for miscarriage last year". She lives about 400 miles away and has had a steady boyfriend recently but they haven't been getting along.

The sad thing is I had no idea that she ever considered having kids. Why would someone take such a risk in their 40's? Was it an accident? I don't know if she's going to realize that she left the note in the magazine and that I saw it. Should I pretend that I didn't see anything and keep my mouth shut. I must say I was stunned when I found out and I wonder if she ever tried in the past to get pregnant. I couldn't sleep at all last night and my feeling is I shouldn't say anythinga bout the note. She's never been very open with me about her personal life or problems, whereas I used to be very open but now I'm older and wiser and know it's better to keep my mouth shut sometimes about things.

I feel so sad for her. I have 2 lovely kids and it hurts me to see that maybe she always wanted to be a mom, too. She used to say that she never wanted kids and a few of her boyfriends didn't want to continue their relationship because of this. Was this a lie?
Should I keep my mouth shut about finding the note?
