Hi guys,
I am a bit confused and I am hoping someone could give some input - I will be doing a test in a few days, don't want to do it too early, so I thought that I'd get some input in the mean time.
I have been using the app Glow to track my period and ovulation days. My cycle is pretty spot on, 29 days, always on time, no exception. AF was supposed to arrive yesterday, but still no sign of it...so I had a good look at my Glow app this morning and noticed that it had me down for a 32 day cycle this month for some reason and if it had in fact been a 29 day cycle, AF was suppose to have arrived on the 18th already

Is anybody here using Glow? Does it change you cycle lengths at random sometimes?
I am having the dull cramping I usually do just before AF arrives. However, I know this doesn't mean it will arrive, as with my first pregnancy I was sure AF was going to arrive any minute, and I had the same dull cramping for about 5 days - turned out I was pregnant so the cramping was misleading.
Any input? I really want to wait a few more days to test. I have no idea why the app changed my cycle length this month, so confusing!
