I went to see an obgyn for infertility in late November, I was giving the bbt and was told to chart my temp when I got my nxt period now I have always seem to have irregular periods since I started getting them. I thought I started my period dec 1st because I saw blood but I guess I was just spotting for that one day I ended up having unprotected sex dec 5th and now its jan 4th and I still haven't seen my period so my question is was that my real period I saw on dec 1st and could is it possible that I could be pregnant from the incident on dec 5th?
