I had unprotected sex around Oct. 6th, about a week after my last period. Today Nov 9th, I still haven't had my period. I took about 4 pregnancy test in the past week and all are negative. I had weird bleeding around Oct 18th or so, it lasted about a week, but definitely wasn't my period. Mine are normally heavy and have horrible cramps. This was light, light enough I could just use a pad. I'm exhausted all of the time, and could sleep at least 12 hours during the night and still sleep more during the day, which is not normal for me. I've noticed the past couple days my urine has been cloudy too, I just recently started working out again and read that it could be dehydration. If someone could please help me, could I still be pregnant ? If not whats wrong with me ?
