I had posted in here a little while ago asking when the earliest you can test was, i'm just really not sure the exact date my period is due. I am fairly sure it comes by the first week of the month but not one hundred percent positive. Could I take an early result pregnancy test now? Lately...my boobs have been extremely sore, and i have been getting occasional cramping as well as headaches/dizziness. Any input would be appreciated...i'm planning on taking a test within in the next couple of days.
