One dominant follicle seen!!

RUX • TTC for second baby 😊😍

Today is CD7 and luckily there is one dominant follicle seen measuring 16*13 mm!! I know its not bug enough to concieve but am hoping it will increase till CD10? Also is there any chance that this follicle will rupture sooner and I won’t be able to concieve? I mean before it gets bigger what are the odds of getting rupture? My doctor said this might grow further or might rupture in this size it self which will make us almost impossible to concieve with this one? Any suggestions, experience ?? TIA❤️❤️
