That was a misconception of mine (the apps dont work) and I got the ClearBlueEasy Fertility Monitor - now its pricey but my OB highly recommended it. It might just be that your calendar is off by a few days.
Also, if you are over 30/35, take your hubby in with you to get a Sperm Analysis - just to make sure you are playing with a full deck. Best of Luck!!View Thread
It may be an issue, but the best bet is to stay still for a while afterwards. When you lay on your back, your uterus is naturally tilted to promote flow towards the egg. Stay laying down between 15-20 min and it may help to place a pillow under your hips. (Place a towel over it if you feel you are losing some of "it")
I have also been told to try to pick up your legs (your bottom against the headboard and feet right up) and crossing your legs at the ankles to try to keep "it" in. One mistake is trying to tighten your kegels - you may actually end up pushing more out.View Thread
