My period 2 weeks late and i have lots of cervical mucas is this a sign of pregnancy or hormonal imbalance?

Unclear: If you're period is 2 weeks, late, take a test. Home pregnancy tests are very accurate, then you'll know 100% for certain. Discharge isn't a good marker, necessarily, of early pregnancy. But being 2 weeks late for period is. You are right to suggest, however that discharge changes during menstrual cycle. Assuming a normal cycle, estrogen predominates when mucous is thick, not ovulating.
