My husband and I have been trying for 10 months and I didn't think it was going to happen

My husband and I have been trying for 10 months and I didn't think it was going to happen. One key pregnancy clue I had was a few days of unrelenting heartburn. The OB at the time said that it would of been too early to experience that . (That would of been a few days after my normal ovulation) That really bothered me because it's not my normal to get heartburn. My advice, don't just take a doctor's advice as golden. Study and learn and find it on other sources with anything ttc
