We tried for the next 7 months to no avail. I then discovered the stork, so I gave it a try. The first time it worked perfectly, the second one we did malfunctioned but that's because I didn't push the correct button before pulling it out. ..make sure you follow instructions!! 2 weeks later, I have my BFP! So long story short, try this product! It works! Just be sure you follow the instructions exactly so it works correctly."
