AF due 3/22, cycle buddy?

I'm Kim and I'm 23. AF is due around 3/22 according to this thing, this says I ovulated 3/6-3/8. I felt that I was on the 6th but didn't teat until the 7th and the test was negative. I felt that I might have been last night even though this doesn't say that I should have been! I was on mirena for five yrs, got it out and had nexplanon but with what felt like eternal bleeding I got it out in Jan. My bf and I are TTC with no luck yet. My last AF was my first off of BC so I'm not 100% what my cycle length is, but from the one I had in Jan it was 22 days. So hopefully it comes around the same time as last so I can get a schedule to track this! Any advice is welcome and any cycle buddies also!! :)
