Confused, help anyone?

Last week was my fertile window. And my spouse and I tried as much as possible.  But as of Monday EVERYDAY I woke up nauseous. Yesterday, I come to find out I'm tender in my area, it felt like a yeast (tho no desperate itching) just a little burn in the outside and a bit of discharge ( not as smelly as a regular yeast infection) I treated with a One day Monistat, even though I would of preferred treating with a homeopathic solution. I caught it on time so I just grabbed the Monistat. Has this happened to anyone? I'm still feeling nauseous and I just want it to go away.
