I wouldn't want to worry you but I will give you my story, or rather that of my children. After that you can decide if any of the info is relevant and whether or not you decide to take matters further.
After my son was born, it was noticed that he had lip pits. We thought nothing of it, his mother had them and guessed they were hereditary. When he was about 3 years old, as part of an ENT consultancy about his hearing it was noted that he had a bifurcated uvula.
Genetic and family tree studies followed and it was ascertained that he had Van Der Woude Syndrome.

My daughter, 5 years older than my son has no signs of the syndrome but we have been told that both children have the possibility that their children may be born with the syndrome and all it entails.
My son has had corrective surgery at Alder Hey firstly for the uvula, then later for the lip pits (his were abnormally large and deep).

The genetic research revealed several instances of cleft palate complications on my ex wife's side, nothing on mine.
To put your mind at rest, most cleft palate's these days are often picked up during the 20 week scan and as erin-x says, cleft palate/lip corrective surgery these days is fantastic, with any scars becoming almost invisible by the time the child reaches secondary school age.
With your own history of cleft lip it could be worth doing a little family research, just for elimination if nothing else.
