We’ve been TTC now for 6 months, we’re late 20s and both healthy. I got the Ava bracelet in about a month ago and I had been following 3 other apps besides this one. The main one I thought was right was Ovia but the Ava bracelets prediction now has been earlier than that app said so I could’ve been missing the right days every month. Praying we conceive a healthy baby soon with this great technology tool to pinpoint our best days to try.
