Hello,
There are several reasons why a woman have delayed menstruation and this could be due to unhealthy diet, stress (emotional or physical), sudden weight gain or loss, caffeine, alcohol, and smoking. Gynecological conditions like polycystic ovarian syndrome (PCOS), and uterine cysts or polyps, can also bring about alteration in menstrual cycle. However, pregnancy is still the most common cause of delayed or missed period. At the early stage of pregnancy, the level of circulating HCG may still be low to be detected by routine urine pregnancy test. But you can do a serum pregnancy test (more sensitive than urine pregnancy test) to know the exact level of your HCG 1-2 weeks after ovulation or after a missed period. However, it will be better if you seek consult to an OB-GYNE specialist so you will be thoroughly assessed.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks, what could have been the cause of my last period? I only bled for a day and a half and now this one is late..
I have considered doing a pregnancy test because I do have unprotected sex quite regularly..
