Curse you Prometrim

Father's Day I took a home pregnancy test to see if I was pregnant. The result was negative. That evening I start some spotting. I thought okay AF is going to arrive. Since then I have only had spotting. So I tested again thinking that it was implantation, lo and behold another negative. I called my RE's office today and they said that it is probably my Prometrium slowing things down a bit. I stopped that on Monday. The nurse said it could take a while for it to get out of my system. So this spotting is just a prelude of what is to come. If I don't start flow over the weekend I am to all the dr's office. Please pray that I start or either get a positive test. I just wish something would happen already.
