Hi. It is very hard to know as PM symptoms are exatly the same as pregnancy symptoms... I had "pregnancy " symptoms for two weeks (very sore nipples,enlarged breasts with blue veins,etc..) and I was not pregnant. I would advise you to do a HPT (early pregnancy test should be used) and if it is negative maybe go and get a blood test done or wait few more days and test again. The best you can do if you are hoping to be pregnant is to take care of yourself,no alcohol,coffein,etc.... and also don't get your hopes up (as I did) because you can be real disappointed if it turns out differentely....If you are not hoping to be pregnant see your doctor a.s.a.p. All the best!
