is this normal?

So I had my period about 2 weeks ago and something did not feel right about my period.. I don't know what it is but I took a pregnancy test before my period and it came out to be negative, well 2 weeks after my period I have been having cramps in my abdomen like I am about to have my period again but the cramps only last for a short period a day on and off and I have been having white discharge, it has not been really sticky but also for about 2 weeks now I've been kind of feeling sick to my stomach after eating, almost like I haven't even eaten in a while and my stomach is mad at me, well this has not happened before and my abdomen is sensitive when I lay on my stomach, it's like telling me to find a comfortable position but I am a stomach sleeper. Has this happen to anyone else ?
