How did you feel after the first injection of Betaferon?

Yesterday it was my first injection of Betaferon. Firstly it was 0,25 and they told me how to gradually increase the dose. They gave me the injection around 13:00 and i had temperature like ... 37,1 arround 20:00. Today i am fine but i have same temperature arround 37,1 - 37,2 degrees celsius. I don`t have chills but normaly, my body temperature is arround 68,9 celsius. So, it normal to keep my body temperature little bit high after the first injection or it will get high after any other? I mean, they gave me the injection yesterday but today, i still have high temperature. Little bit worried...
