FALLBACK RISE???

Mary 🩵🩵🩵👼🏼👼🏼🤰🏻

I had a very positive opk on cycle day 13, along with a clear blue digital solid smiley peak, still had a positive cycle day 14, wasn’t as dark, then cycle day 15 it wasn’t positive anymore. I had a huge spike yesterday morning but today it has crashed! Having brown spotting as well today. Wondering if i even ovulated?? Or could it be a fallback temp? Ugh hate doing all this.
