Pregnancy symptoms after 2.5 months?

If you missed your period or it was different than before (by different I mean mostly that it was lighter and shorter than usual) there are possibilities that you are pregnant. On the other hand, if you didn't miss your period and it was regular then you really don't need to be scared or worried. Pregnancy symptoms can be the same like some other symptoms that are involved with headaches, nauseous, sore breasts etc. I had this once, so I think that I know pretty much good what am I talking about. Did you recently travel to some trip, vacation? Did you change climate? This can affect you and your body.
