Hi and thanks for using the forum.
It is not unusual to have an "off" period every now and than, so I would not be too concerned yet. You are right that the dark blood is usually "old" blood. Wait and see what happens over the next few weeks. If your period is off again next month, you may want to see your Ob/gyn to be sure that everything is OK. Good luck.
Hi, I'm not a nure or a doc or anything. I have that problem too sometimes, but i seemed to go away. I switched my pad and tampon products around and it seemed to do the trick for me. Sorry if it's not too helpful.
Ok I meant July 19 lol and its been pretty hot lately
