Don't worry about it. I had two CPs told me the same thing as well. I forgot who the other one was but the other one is Gail. That was before the break up when i called about our jobs and where we would go from hereon and right off the bat she said he's the guy i will mary, move in together in XX months, jobs in XX weeks, very successful but before we hung up she told me to be careful because i might get pregnant. O_O.... thinking back to that, seriously if you are active then of course there will be chances that you might get pregnant. If you are not careful of course you will so really, saying that statement is like not saying anything at all. And of course when i called her back after he broke up with me, she did a 180 and said he wants to date other people etc. Those two calls were made within two weeks apart so really, if she's accurate, why didn't she see the break up happening? Gail is off my list. Not because she said something negative, but because it just doesn't make sense. If she can help you find lost objects as she claims, that means she can 'see'....but she didn't see the break up coming, so i don't trust any of her future predictions.
Don't worry about the pregnancy thing. Plus they are not suppose to give you health related advices and pregnancy is a pretty big health related issue if you ask me!
