My exact day I was supposed to ovulate was last Monday, May 7th. I had sex on the 3rd and the 5th, a couple days before. And since that day I have had heartburn , back aches, and sharp pains on either side of my stomach ( cramps ) and leg aches. Yesterday I experienced sharp pains in my chest under my breasts and now noticed white little things around my nipples. I have exactly a week from today until I am supposed to start my period . Any ideas on what might be wrong? I have felt tired and weird this whole time.
