20 day cycles

I was able to regulate my periods this year with some weight loss and vitamins , now they're like clockwork every 20 days . My question is , is 20 days too short ? Will I still be able to conceive if I supposedly ovulate AS SOON as my period is over ? I'm very excited that my periods are back to normal but now I'm worried I won't be able to conceive with it being short like this .
