Something really happened ! Need your opinions ladies!! Thank you bunches

So i got off my period about 3 days ago. Yesterday I had a little bit of brownish pink spotting when I wiped but nothing else. Now the twist. Yesterday and tonight I threw up. Didn't hurt. Didn't feel sick before hand, just kinda came up. Any ideas? I never ever throw up. And afterwards I felt better too. I have no fever, and I'm not sick. Any ideas? Or does any of you ladies have a similar story?? Thank you ladies
