Hey what does it mean when your period not coming on but you spoting?

Not ovulating: Check a pregnancy test first. Spotting without a normal cyclic period means that you are not ovulating. There are lots of causes such as pcos, thyroid disease, too much weight gain or weight loss. Schedule a visit with your obgyn so they can go through your history and run some very basic tests.

Pregnant?: It could mean pregnancy or infection or lack of ovulation among other things. Check a pregnancy test and see your doctor.
