My period started on the 18th of February.....ended on the 23rd....I spotted for three days starting the 26th. I have almost every symptom of pregnancy....tension headaches, exhaustion, crampyness, etc. Could I have ovulated early, or could I have gotten pregnant last month and just not known??? The tests I have taken all say neg so far. But I'm not supposed to start my period for another week. Please give me some advice. Thanks!
