Now I'm wondering

Teresa
Been ttc for 5 monthes. Got my period on the 12th like always. But my cervix never dropped I'm sopossed to be ovulating in a few days and no sign of it. I usually get little pains and discharge right before ovulation my cervix has been high for a month now. And today woke up with a horrible headache and very nauseous now I'm wondering. What's everyone think.
