Ok, here is my idea. It's like the monitors diabetics use. Only it looks for the homones. SO, you switch it to OPK to test for ovulation, then to HPT to test for pregnancy. Not only that, but you can continue to use it to watch your numbers go up to give you a peace of mind. Why hasn't anyone invented this? I would pay $100 for one. Yes you have to ***** your finger, but what is alittle ***** compared to the needles they use in the lab? It could tell you almost as early as what 5-6DPO? Just test everyother day and see if the numbers go up. If they do then you are PG.
