Has anyone fallen pregnant with a nightnursing toddler?

[Per16]

Hi girls - my husband and myself have been trying for no 2 (this is our 3rd cycle) we have a 26 month old toddler who has only got 4 teeth so is teething like crazy and is refusing to eat and only have boob all day and all night, I have had 2 periods with 31 day cycles but I have not had any ovulation signs (absolutely no CM etc) I was just wondering if there is any point in actively trying to concieve while she is still feeding even though I have had 2 regular cycles? hmmm Has anyone fed alot and still fallen pregnant? Are there other signs of ovulation at all? thanks girls sorry for all the questions!
