Symptons of pregnancy? Help..?

In all honesty, if you are pregnant, you are too early on to be having those symptoms as things related to pregnancy. Nausea doesn't usually occur until around 6 to 8 weeks pregnancy. Don't get too caught up in the emotions thing either because that could just be a symptom of pms, especially if you are getting worked up about the possibility of being pregnant. Sometimes we trick ourselves into thinking that we have symptoms that we aren't having, or we look for things and we want it to be because of pregnancy. I'm not suggesting that you're not. You could have a very sensitive system, and these could all be pregnancy related. These are symptoms that are common in pregnancy. I just think that it's too early for these things to be pregnancy related when you haven't even missed your period yet. The best thing that you can do is wait it out a couple of days and take a pregnancy test. Be sure that you take it first thing in the morning. Good luck to you! Either way, you need to call your doctor, because diarrhea for two days is never a good thing. Get yourself checked out! Best wishes!
