So...I have been lurking these boards for about 3 weeks now.  I am just now getting frustrated enough to hear other people's stories, so I feel less crazy!! So here is my situation.  I had my last period January 4th, 2013. The beginning of February rolled around, still no period.  I had sex on February 3rd and February 15th. (I thought my period was coming around the 15th because I had cramping, but it didn't show. Maybe ovulation cramps?  I do get those.) I took a couple of pregnancy tests (me and my "partner" have unprotected sex, but we use the "pull out method" which he is pretty good at, never a mishap) and they were negative.  Took a qualitative blood test on 2/24/2013.  That was negative too.  On the 27th of February around 8:30pm, I went to the bathroom and there was pink spotting when I wiped.  The next day, by late morning, I was bleeding like a normal period.  On the 1st of March, I was still bleeding like a normal period, small clots were present and all.  I even had some cramping, although only the first day of bleeding.  At one point there was a round, pinkish color thing in the toilet.  I couldn't figure out what it was so I just flushed it.  On the 2nd, around noon, everything was gone! My periods are usally 4-5 days long with another day of spotting.  I am so confused as to what could be going on with me.  I still feel very light cramping on and off and a kind of pulling sensation and pressure in my lover abdomen.  Any advice??? Could I still be pregnant? I am going to test Sarurday again to be sure.  But if I am not, what is going on??? I can't imagine that was a normal period after being so late.  Why would it only last 2 days?? I do not really keep much track of my periods, however, I usually have any where from a 29-32 day cycle.  The only time I have ever missed one in 15 years was when I was pregnant with my daughter.  The 2 or 3 times it has been thrown really off have been when I started new exercise routines.  I am usally pretty regular otherwise.  I hope all of this makes sense.
