<human>: Can you condense the text into a few key points?

Question that I couldn't find the answer to! So, I have a friend who was dating an HIV positive man, and she was negative for it. I advised her to avoid having sex with him, and to at least use a condom every time they do have sex if they choose to. Well, recently she found out that she is pregnant (has been for about a month). She will likely (hopefully) be getting an abortion soon, but that's not what this thread is about. I was reading about HIV to try and learn as much as I could (I figure she won't), and saw that transmission rates are somewhat low (according to wikipedia, receptive penile-vaginal intercourse has a 0.1% chance of transmission, but I am pretty sure that is with a condom). BUT. Since she is pregnant, and told me that they rarely use condoms, what are the chances that she is positive? I've been trying to get her to go get tested, but she has been procrastinating.
<bot>: friend was impregnated by her HIV positive boyfriend a little over a month ago. How likely is it that she has HIV? (I thought it was definite that she does, but now I'm not so sure)
