I had my period July 22 - 27 , 2013 and my next period should have came  August 22nd, 2013 but it is late by 5 days. I took a pregnancy test on August 22nd, 2013 but it showed negative. I am very worried that I could pregnant but I have had overprotective sex in two months now. I am worried.
Hello, You need to repeat the pregnancy test after 1 week to clear doubt. Hormonal imbalance, mental stress, pelvic infection, over wt can cause late period. Kindly, consult with doctor to induce period with pill in the absence of pregnancy. Practice safe sex in the future. Good luck.
