Hello,
I am on Mirvala 21 birth control. I have been really stressed out and have been having diarrhea for the past week. I have had around 2-3 very liquid stools a day. I take my pill at night, and never miss one. I have the loose stools in the morning, around 12 hours after I took the pill? Do these count as miss pills?

12 is most likely going to be enough time for your body to have absorbed your pill completely; you don't have to treat these as missed pills. Any time you're worried about your pill's effectiveness being compromised, though, you can always use a backup method of birth control as well, such as condoms; that way you have two forms of protection so if something happens and one form is impacted to some extent, you have another one picking up the slack.

So if it is 12 hours, it doesn't matter about how many I had in the day?

Yep! The pill is absorbed within 2-3 hours of being taken, so having diarrhea 12 hours later is not going effect it.
