Should i be worried?

So i was on the pill for 6 months but I decided to stop taking it.My first period after i stopped taking the pill was only 4 days late but this month i am 7 days late.My boobs are sore and i have white discharge.I went to the gyno for other stuff but i asked her to take a look and she told me that there is no problem with my ovaries and that i have uterine lining which means that i will have period but we don’t know when exactly.I am paranoid and i am scared that i will never get my period after taking the pill even though that my gyno said there is no problem
