Cycle buddy??? 9/16

Heather
Hi my name is heather. Looking for a cycle buddy my monthly is up for 9/16 to 9/21 not sure how to get all mine to start and end on the correct dates. But I have been manually putting then information in. Because some months it will last longer and some months it will start before for my date I have been tracking it for about 6 months now. :/ and trying for over a year. :( also not sure if this is the correct way to post lol.
