What's going on!

Laura • TTCING baby #3 since November 2011
DH and I baby danced one week before my fertil week, but didn't during because I had a bad cold. We danced again the day after my fertil week, I started spottin and even had 1 or two small clots pass, this was about 10-13 days after my fertil week. Now at almost 14 dpo I am seeing rusty old blood when I wipe. I took a hpt 2 days ago, and it was negative. I'm about 3 days late now...
