i came off bc in november and have had fairly consistent periods lasting 4-5 days.. they have been off by a day or so according to when i should get them.. this time i got it and it was 5 days early.. but only lasted for 2 days. it was very light but still required a pad for my own sanity.. it was officially supposed to start yesterday but started this past monday instead. today i tested with clear blue opk and got a smiley face. i shouldnt see that for another week at least. my opk test results have been consistent with the apps prediction within a day or so except right now. what could be happening? this is the first time i’m really at a loss as to what’s going on please help!
