A lot of sypmtoms of pregnancy and PMS are the same. When there's a possibility of being pregnant a lot of women are more aware of these symptoms and they seem to be more pronounced--sore nipples, food cravings etc. I'm not saying that you are or not pregnant. You can tell me every symptom of being pregnant but you're not pregnant. You can tell me that you have no symptoms of being pregnant but still be pregnant. The signs you have told me are indeed signs, but I can't say for sure one way or the other without a positive pregnancy test. If you're a or two late take a pregnancy test with the first morning's urine (more concentrated). A lot of different factors go into if you're pregnant--how fertile you are, if you were ovulating, the sperm count etc.
You can get a free test at pregnancy centers Just type in your city and state and they will show you a list of centers near you. They also have a toll free phone number, email, and innstant messenger through AIM.
Let us know how you are doing. All questions are welcome. I've included my email.
