Cold, sleepy 24/7, no energy, yellow and today I tiny hint of brown cm...

Fanistar • 2 boys ⚽️ and now a girl 🌸 My husband ( who wants an open marriage now that we had our baby 😤) and I have been TTC since late August 2017. Had a miscarriage in February 2018. Found out I was pregnant again at the end of March 2018. I'm broken but happy I

AF is due on Oct 31st, but glow changed it to Nov 1st, then Nov 2nd... so who knows. But I last baby danced on Oct 12 and I think I ovulated on the 15th.... since 5dpo I have been sleepy all the time. I'm like a sloth 😂 felt a cold coming on but has not yet hit me... it's been a few days of feeling this way. I feel like I'm about to get a sore throat because my throat and ear are uncomfortable, but not yet a legitimate sore throat 🤔 my temp was 98.9 so not a fever but higher then norm.

The last few days my cm has been yellowish then yesterday it was a lil clear and today I wiped and it was yellowish but with a tiny hint of brown... (only one time) like super light brown.... I hope AF isn't trying to make an appearance this time. Any advice? Or has this happened to any of you before a BFP?
