Low grade fever

I am currently 2 days late. Ive had a low grade (99.3) fever off and on for 3 days. Semi painful cramps since 5 or 6 dpo and extreme moodiness.... mostly crying... at everything. I had a stark white negative at 11 or 12 dpo and havent tested since. Im currently 16 dpo and terrified to get my hopes up. Who am i kidding....they are up. ALL the way up. Blah. Buying another test this evening if I havent started by then. Just venting... cant exactly post my weird symptoms on facebook lol Fingers crossed!
