Hello all. I'm looking for anything anyone has to say with my story.

I had a miscarriage in March '09 and have been trying to get pregnant for the past 5 months. I was suppose to have my period at the end of this past November but nothing so I went to the Doc and got an ultrasound and bloodtest-- everything was normal but no baby. I have PCOS too. About a week or so after the doctor visit I started spotting, I've never spotted unless it was either right before or after my period. I thought I might have had a urinary tract infection but now I'm doubtfull ( spotting doesn't come from the infection). I'm not in the mood for intimacy either, which is not like me at ALL! I've been intimate with my husband twice over this period and the first time I bled almost like a period but then it went away within hours of intercourse. The latest time, nothing happened just the normal spotting as usually for these past weeks. I've taken a pregnancy test within the past day or so and it came up negative. I guess I'm looking for someone that this has happened to for guidance and insight because I'm getting worried a little and if I am pregnant, from reading the other posts negative doesn't always mean negative, I don't want to do anything that would have me loose the "baby".

Help?! I visit the OBGYN on the 29th of Dec. I do have semi tender breasts but I don't know my body well enough to notice any thing else that's "wrong" or different with me.
