Hello my name is Katie and I am 22yrs old TTC#1 with my husband Augie. I have been off BC since beginning of January so this will be my 3rd cycle. This has also been the first month where my period has been irregular. Spotting (light pink and brown on day 1) started on 2-27 (12DPO) and is still happening today 3-2 (15DPO) but received BFN. According to this app, I should be expecting AF again 3/25.
