14 days late

Hello , I'm 14 days late for my period .. I usually have normal periods .. my test have been negative /sometimes super faint positive .

I have had two kids but I was told with my last pregnancy I have pcos .

However when I went to the ER the other day they said that it is highly unlikely that I have pcos if I have had two kids ..

Sooooo....

I have two questions

Can I have pcos after having two kids?

Or could I still be pregnant even tho I'm getting negatives ?

I'll also be adding a picture of my cycle for each month.

And a picture of the test that is a faint Positive.

Also the circled days are when I've spotted very light pink.. I'll include discharge pics too. They will be blured ofc..

The test was from yesterday and today I got a clear negative..
