Hi, my last period was 29/11/19. unprotected sex on 12/12/19. still no period. blood & urine tests are negative. been having cramps on my left abdomen for 2 weeks on & off. what could be the delay. im not stressed since i was promoted & all is well?

Tests are accurate: Pregnancy is the most common cause of a missed period. If not pregnant, other causes of a late or missed period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (especially birth control pills), hormonal disorders, etc… A visit to one’s Ob-Gyn doctor is a good idea if symptoms are persistent, recurring, or worrisome.
