Shall I Wait To Test?

Last Period was 6th May lasted only 3 days (normal is 5-6 for me) Since then have had cramps headaches are sensitive and feel like a whale!! Even my face is chubbier and breaking out in spots! Also recently ive been nauseous and the last couple of days have been feeling lower abdominal twinges! Could this be my month or is it head games :( My period is due in 2 days 9th June shall I wait to test or can I get a positive 2 days before! Xxx
