Don't talk about my baby!!

Ok so We went to Walmart tonight and we were at the red box looking for a movie to watch and this lady comes up to us. At first we had no clue what was going on. Then she starts asking us if she could pray for our family. Honestly that kind of stuff makes me uncomfortable. Not that I'm against god but you just don't do that to people. So we say yes anyways so we don't seem rude. The lady starts praying and making all these sounds that to me don't sound like good sounds. And personally I don't need to be feeling like something bad is about to happen when I could literally go into labor any moment now ( I'm 38 +2). I think that would make any new mother to be really freaked out. So while she's praying she starts point at my SO and saying "it's because of you". Wth!!!!! And then she starts saying we need to get our baby dedicated before his first year is up and that whatever happen is because of my SO. She told us that she had the gift of a prophet. So now I'm like great... I thought praying for people was supposed to be a good thing but now I feel like my baby is in trouble. Something this pregnant girl could have really done without!!!!! And now I feel like a horrible person for being so freaked out about someone praying for us.
