I ended my period on the 27th of June. I had unprotected sex on the 28th. I bleed a little after that. Most likely from me having sex. Lately I've been feeling sick off and on. Yesterday my body woke myself up at 730am to vomit. After that I took a nap, woke up and was fine. I've been moody and having cramps. I'm not suppose to start till the 22nd. I've been having white milky discharge. Anyone have any idea what could be wrong?
