Hi everyone! I have a very regular cycle and it always remains the same. I have been trying to conceive and have been using Oura to track those ovulation days. It had first told me that I ovulate during the week of May 1-10 with the peak being the 5th. We had tried on those days but then a few days ago it switched the dates and keeps pushing it back with no confirmation of ovulation. Has this happened to anyone? Im apparently 5 days away from getting my period. Seems to be like a long phase.
