Ppl say things, some say it like sadzz says - 3 weeks after the wedding. "OMG, you are not pregnant yet?" Weirdo's.
I've had random aunties whom I do not even know come up and ask me directly if I'm avoiding having kids or if I am having problems, and what sort of precautions am I taking of any and what "treatment" I have taken to rectify the problem of trying. I was gobsmacked. So shocked I couldn't reply!
Best thing is to ignore and certainly do NOT give them any facts, i.e. if you are or are not using precautions, if you are planning to have them in a couple or years or whatever.
If you can ignore them without a response, then ignore, otherwise do as the others have said, say when Allah wills then it will happen. There is nothing more true than that!
Glad to hear I'm not the only one who has to put up with this.
