the other ladies are right. you NEED to take an hpt. so many early pregnancy signs/symptoms are the same as pms, getting sick or a number of things. i get awful cramping and back pains every month.
the ONLY way you are going to know if you are pregnant is if you take an hpt or get a blood test done. wait until your period is 3-7 days late so that you get an accurate result though. but taking the test is so much easier than stressing about it.
Have you taken a pregnancy test? When is your period due?
Pregnancy symptoms are very common symptoms. Nausea and back pain can be associated with any multitude of other issues not pregnancy-related. A pregnancy test is the only way to know for certain. Don't read too much into the symptoms. ;-)
i know u are worried all i can do is say take a test..those are preggo signs..but they are also signs for tons of other things
