I got my period june 8, 2013 and since then I dont know when my next cycle come b/c I have irregular cycles I guess. But monday july 8, 2013 I got sick out of nowhere around 5:30. I had a bad headache, threw up, lost of appetite, I had a high fever but my body was cold. Then july 12, 2013 I had a stuffy nose all night, runny too, headache. Could this be a early sign of pregnancy? I am trying for my 1st baby but no luck. I had sex all thru june and twice or three times for july. Do anybody have any idea what im going through? Or has anyone experienced this when they was pregnant?
