Well, I had trouble getting preg the first time...and the doc told me to have sex missionary position only and to not get up for 10-15 minutes..to give the sperm a little help upwards. The other thing is I know you are anxious but don't take the HPT before your period is late or else you could be preg. but not know it. Those tests aren't very good until after you have missed Aunt Flow. The baby can sense the mom's emotions and you don't need to be upset. Sorry i couldn't be much help.
Smile, life doesn't last that long.
