My coworker and his wife had been trying for 2 1/5 years to get pregnant and nothing. Until his wife started taking this supplement more than a month ago. Now she is 5 weeks pregnant! So, he knew my husband and I had been trying for 2 years also and recommend this. I heard it also helps with your periods. I have horrible periods. I've been taking it for 1 week now. Hopefully it's my husband and my turn to be preggos. :)
