Any insight?

Summer2017 • My husband and I have been married for 3 years and have been TTC ever since. Hoping for a 2017 little miracle 👶🏻
Alright ladies just looking for any insight on anyone's experiences. My cycle is irregular ranging from 28-35 days. Last month my cycle was 35 days and I'm creeping up on that number soon which isn't normal for me having two consecutive months of the same number of days. I am 12dpo and a couple days ago had some light brown spotting. According to glow AF isn't due until Tuesday. I know a hpt is the only way to know 100% but I don't want to test yet. If we're not pregnant this cycle then we're doing <a href="">IUI</a>. Does my chart or any info show any insight to the possibility of having conceived?TIA
