Blood in face. Risk?

Please help me. The CDC has scared me to death suggesting I get on PEP. I was downtown Denver today and a homeless wormen, with only like 3 teeth, and obviously high on something, grabbed my arm and started telling me how she had AIDS and was on the streets and needed money for her baby and so on. I stopped because I didn't want to brush her off as if she didn't matter. But all of a sudden she started coughing up a bunch of stuff and a few blobs of cough/saliva and whatever else was in her mouth and throat hit me in the face and two or three small drops hit me in the eye. I'm sure you see where I'm going with this. I am afraid there may have been blood in her mouth or throat which hit me in the eye. I'm pregnant myself. In Denver we have a nurseline at the hospital and she told me not to worry, but I am afraid because the CDC didn't have that opinion. What should I do?  Am I at risk? THANK YOU!!!
