Track a miscarriage

For anyone who has had a miscarriage (I'm sorry because I know how hard it is) but how do you track in the app. I have had 2, found out about the 2nd today :( if I put them in as periods they will throw off my cycles and my dates. If I don't put them in than it will look like I had an extra long cycle. Just confused as we want to try again as soon as we can but want the app to be able to track correctly. Thanks for anyone's help.
