Opinions before I freak out please!

Chanel

So my period finally went back to normal since having Mirena removed last October. I usually start on the 10-11 every month..

Now, it is the 17th and I still haven't started..

I took 3 pregnancy tests yesterday and they all came up negative! They should be accurate after this long, right?

I have also had a discharge that is a bit milky and coming quite frequently.

Does anyone have any opinions before I freak out and see a doctor?

TIA for the help.
