Any Runners in Here?

Melissa
For the past week I've run a mile 3 times and all at least took a minute or two longer to complete than normal. usually I run between 1 and 3 miles and my mile is about 9:04 at its best. Now I'm running a 10 to 11 minute mile. I guess I'm wondering if this could be indicative of conception. I know it sounds really lame and silly, but I remember with my son I became exhausted early in the pregnancy and then it kind of went away. Since this weekend I've been feeling exhausted and very moody... I'm not testing until the 28th so I won't actually know until then.
