I ovulated April 3rd and for the past 3 days I have felt perfectly fine during the day but in the evening I instantly get a wave of being nauseous and sick feeling for about 2 hours and then I’m fine. Has anyone experienced this? I don’t have a fever or anything, but with my nauseous this evening I did have a horrible headache. My breast feel heavy but have not had implantation bleeding. I have had lotion like CM for a few days but I had that last cycle as well. Any thoughts?
