I missed my period, which is usually regular, by 4 days. I went out and bought a few at home pregnancy tests. I tested one the night I bought them and within 30 seconds I could tell the test was positive. Then I tested the other early this morning to just see if maybe the one before was an error and this one would be accurate? Both came up positive. I haven't had any symptoms really besides light cramping on and off for the past week or so. Is this normal? Could my tests be wrong? Will I not know for sure untill I go to a doctors appointment?
