So I was using digital and cheapies to track my first cycle since my MC in January. This is what my March calendar looked like.
I don't really trust the digital ones anymore since I think they gave me false positives in the past, so I kept taking them even after it said I was peak and I have gotten a blinking "high" fertility for the last week, after it said peak on the 30th. Anyone else been in this boat before? Seems like if everything was correct and I DID ovulate during that week, I'm only like 7dpo so it's too early to test. Anyone?😩
