When should I seek help?


I've posted before but didn't get much advice and now I'm at my wits end. I've been trying to conceive baby #2 for 2 years. I had a miscarriage in January of 2016 and a ruptured ectopic in June that resulted in the loss of my right tube. I was told that I could still conceive naturally with one tube although my risk of another ectopic would be about 30%. Ive been trying ever since. It'll be 10 months in April and have had zero luck. My cycles are very regular, 28 days on the dot. My question is, when should I seek help considering my history?
