13mm follicle on CD 3?

Kylie

This morning I had my ultrasound for CD 3 and he found one follicle that measured 13mm. He said it's bigger than he would like and/or expect so he thinks it's either the one from last cycle that didn't get released despite the trigger (on the same side as last month) or a very fast growing one. Either way, I was counting on having a week + because my SO and myself will actually be in the same country starting next weekend through the 1st of the year....now I'm afraid if its a fast growing one, we will miss it. Also....should I be nervous that only one ovary has produced any follicles?
