I need help ladies. I don't understand ovulation and my periods.

Last month, my period came a couple of days early (never happens ) and lasted roughly 2 days. During this period I had NO pms. No cramping. No headaches.nothing.

So the period ended and here I am in my "fertile week" and .....

Now, I've been spotting for 6 days (browisg pink ) and my period isn't due again for another 11/12 days. .around the 1st of July.

Bloat.gas.preassure .heightened bbt.

What could be going on here?
