My husband and I have been TTC for 7 months now. I have been using a digital ovulation tracker and we have had sex at the appropriate times for the past 4 months. The smiley face appears and we have intercourse that day immediately. Yesterday, I got my period 10 DPO which was early for me. I really thought we would be pregnant by now. My husband's uncle told us that he had to go on OTC vitamins to help his sperm. He had a low sperm count and morphology problems. He said it was a possibility that it was a hereditary issue.
