Several of us girls have been trying to get pregnant again and we never had a problem before. Then about November or December 2012 we just couldn't get pregnant using the Onduty. Our guys thought something might be wrong with th Onduty so they went out and got another and still nothing for anyone. Also, three of my friends who were already pregnant around end of November-December all of a sudden found themselves not pregnant and without a baby. We also thought lag may have something to do with it but not for this length of time. On one occasion I went to the clinic and they said we now needed to take pills but i think they were putting me on. So, is anyone else beside my friends and i having this problem???? We sure coud use some answers ThankYou. Sincerely and respectfully, Rocalina Blackheart---You can find me in search also.
