may be a stupid question but...

My husband and I are trying to conceive our first child. We haven't been trying long but after reading some advice on here, we have decided to just enjoy each other and stop preventing, paying closer attention to my ovulation cycles. Though the chances are low, if we happen to conceive just a few days before I am supposed to get my period( 5-6days) will I miss that period or have it as normal? Again I'm sure that's a stupid question but I've not had any experience with this.
