moh planning to get pregnant

I think you just need to wait and see what happens. Neither one of you should have to change major life events to suit the other. Don't change your wedding date if you don't want to but equally don't expect her to change her baby plans. She may decide to wait or try earlier without any prompting anyway and babies are so unpredictable! Just because she's aiming for a certain month or even small block of months doesn't mean it will happen like that. Not trying to put a negative spin on her conceiving but there's just so many factors and no guarantee that she'll fall exactly when planned. Also she could well be bridesmaid until quite heavily pregnant with no major impact on your day (dresses are so widely available in accommodating styles or same colour, different styles) and even if she has a fairly young newborn it shouldn't affect her being bridesmaid (probably easier than if she had a toddler!) There is obviously a window right around when she is due and when baby is very new that would make attending, never mind being a bridesmaid impossible but it's possible she'll make the decision herself to try and avoid this now she has your date. She probably didn't intend to cause you any stress or upset by telling you her plans, I imagine she just wanted to put it out there so that any pregnancy around that time wouldn't be a total shock. I hope it all works out for you both x
