About a week ago.. I stayed up until 2 AM..Right when I went to lay down I got extremely nauseated. I layed there for about a half hour before I decided to get up. I went and layed on the couch and still didnt feel well. Around 4 I went back in the room and eventually fell asleep. I woke up around 930 and ran to the bathroom to get sick (It was awful and it was alot) But after that I felt fine. Then later I felt like I had a fever so I checked it and it was 99.5. I haven't thrown up again but ever since I've been getting nauseated alot. And my temp today is 98 something when usually its 97. Is it the flu? Or pregnancy? I can't go on missed period..I have PCOS and Cysts on my ovaries and havent had my period in a year..So I thought that I could not get pregnant..But now everyones saying that Just because I dont have my period does not mean I am not ovulating??
