What do you think the symptoms are?

According to glow I ovulated ever since yesterday and today is my last day of ovulation week. I’ve been having light brownish and cherry red bleeding for 5-6 days and it stopped ever since yesterday. Then today I’ve been feeling like I’m starving myself like crazy. I’ve been eating so much lately and this morning after my breakfast, 2 hours later I felt sick and wanted to puke badly. Went home and ate again then had my dinner and after 2 hours I felt sick again like I feel like puking so bad and have a horrible headache. Need some advice what do you think it is.
