Today is Sun 6/21. I got what I thought was my period on Thursday 6/15. I bled normal for half a day and spotted when I went to the bathroom for 2-3 days after that half day. I have had a severe headache and felt nauseous since 6/15. I took a cycle of femara but have been off it for 4 days so I shouldn't be feeling nauseous from the medicine. What do you think? Is it just in my head or could this be IT?
