Skipped Period ?

Hello So i was supposed to get my period on April 14. But here it is may 4 and nothing Ive taken test after test they are negative. This has never happen before. Also the week when my period was due i had lots of discharge and once i thought i saw a bright pink spot after wiping. Going to the doctor today to see why i skipped and period. Has this happen to anyone else before. Prayers are appreciated its been a long year of trying. Thank you.
