It sounds like you have not had unprotected sex. All of those symptoms could be from the pill, and your temperature varies throughout the month which is why when you are trying to get pregnant sometimes you take your temp every morning to help figure out when you are ovulating.
However. With the slight temp increase, the frequent urination and only going a little, I wonder if you might have a urinary tract infection? If you get any pain or discomfort with urinating, please see a health care provider right away for a urinalysis and some antibiotics.
Unless I'm missing something, you aren't pregnant. Thanks for writing and good luck.
