*TMI* 13 DPO Brown Spotting HELP

Elizabeth • Trying for our rainbow baby - #pelzwedding2014
This is my 3rd and final round of clomid before we move on to IVF BUT I'm praying/wishing/hopping the 3rd times the charm. Has anyone experienced brown spotting and gone on to be pregnant? 
Timeline 
O - cd 16 or 17
12 DPO - BFN + minor brown spotting midday and then nothing at all the rest of the day/night
13 DPO - didn't test but after work I came home and when I wiped a tiny bit of brown "jelly" like discharge came out. 
My period is due either today or tomorrow according to the 72 apps on my phone 📱 
Any advice is welcome 🙌🏻
