I had my period Jan 4. I usually have a shorter cycle than most (around 26 days). I ovulated between the 14 or 15 and the 16. I was intimate with out withdraw on the 16th and 18th. On the twentieth I had one bit of clearish discharge when I wiped in the bathroom with a streak of dark blood in it (implantation?). I had mild cramping the twentieth- current. As of the past 5 days I have been nauseous, have heartburn, broke severely in odd places (back, shoulders, neck), have mild cramping, mood swings, flushed face, etc. I went to Dr. and had a test today... neg. of course. They do not have early detection tests and said even if I was pregnant they wouldn't know. Does it sound like I may have had implantation bleeding? Do early detection tests work for most people? Do I sound pregnant? It is silly. I feel like I am.
