Hmmm... i would definately be off to get a test. Sounds to me like you may be UTD! That kind of blob could be from the plug forming.....

It is weird being your on the pill, cause as far as i know, the ONLY reason when on the pill as to why you skip a "bleed" , as its not a real period, is if your pregnant..... and has been that way for me in the past!

Good luck... let us know when you test!
