I have been having lower back pain, mostly on my right side. Ive been using the bathroom a little more than normal. Ive found myself blowing up on people more often than normal and seem to get upset easier. My period is supposed to come on the 22 so i havent missed it yet, but could i be pregnant?
There is no way to tell if you are pregnant from those symptoms. Too many other things could be causing them. Sure, it's possible, but to answer over the internet is just taking a 50-50 chance of being right.
The only reliable ways to know, is when your normal period is more than a week late, take a home pregnancy test, or you can be tested by your doctor.
