hello, welcome to health care magic Delayed menstruation can be caused by onset of menopause ( you have not mentioned your age), (2) stress, (3)not eating well, (4)hormonal problems ( abnormal thyroid hormone, high prolactin levels- hormone released normally in the brain, high levels of male hormones- females normally produce small amounts of male hormones but in some diseases like polycystic ovaries the level can be higher, other hormones can also impact the periods) (5) excess physical activity or excess weight loss or gain (6) pregnancy The WBC goes up in cases of infection, inflammation, reaction to chemicals or toxins or it may also elevated in some types of malignancy. There are different types of white blood cell which would respond according to the illness that the person is presenting. Your doctor would have looked at these types ( called the white cell differential) to give him/her an idea of what could be causing the increase. The two may not necessarily be related, on the other if your body is under any stress whether physical or emotional related to the increased WBC then it might cause the delay in your period. A haemotogist deals with any disease or condition related to the blood from anemia and problem with bleeding to more serious conditions. It may not indicate a bad diagnosis. He or she will take a full history and may check for symtoms such as fatigue, change in appetite/ diet, pain, weight loss, fever, unresolving infections, any areas of swelling, medication use, exposure to harmful chemicals as well as other complaints I hope this information is helpful to you and wish you the best
