Tonight is the first night of a special honeymoon vacation with my husband, and I noticed a stain on my underwear. This came as a big shock to me, as I wasn't expecting to be getting my period now. The stain was found on colored underwear and is a dark reddish brown (definitely not bright red), although it is probably just a little bit bigger than a dime. I understand that I should show a rabbi asap (although I'm not sure who to turn to while away on vacation– probably the rabbi at the nearest chabad). If there is any advice you can suggest, that would be greatly appreciated.
