What Causes Cervical Mucus To Be Thin And Stretchy After Periods?

Hi, may I answer your health queries right now ? Please type your query here..                                                              I stopped taking BC pills on July 4th. My LMP is July 8th. I noticed that my cervical mucus was thin and stretchable on July 30th and July 31st. Could I have been ovulating that late after stopping the pill when according to the calendar i should have ovulated on the 23-26th of July? I have a 31-33 day cycle
