Honey . . . do not despair! Worrying and stressing doesn't help conceive babies. My hubby and I were trying for alomst 2 years. I'm now pregnant (17 weeks)

From what I understand . . . the most fertile days start about 7 days after the end of your period, start trying then. Sperm can last 3-7 days so, make sure you try every 3 or so days (between day 7 and day 21 of your cycle).
