that this is the month for your BFP. If you DTD on the 9th it is probably a little too early to tell if you are pregnant. Implantation usually occurs between day 6 and 10. The best thing is to wait for 2 weeks (or a close to it as you can!!!) and then do a HPT. Good luck.

ETA - I also agree with Liz28 that there is a good chance that you are ovulating. Do you have a normal cycle length?
