Missed Periods. Pregnancy Test Negative. Could I Be Pregnant?
Assuming regular cycles, if you are 4 days late and a blood test is NOT positive, then you are not pregnant! The most common explanation for irregular cycles relates to irregularity in terms of when you ovulate. This can be normal, but also related to abnormal things such as thyroid disease. If you don't get your period within the week then you need to discuss this with your doctor and get the appropriate warmup.
