Still getting bfn 😔 having every single symptoms possible except breast pain but everything else I have been experiencing. On Friday night I started to feel kind of sick I and since they out of no where I have been having nasal congestion, sinus pain, sneezing 🤧, and 🤕 headache and dizzy 🥴 spells, all these while I still have cramps, backache, nausea, frequent urination, excessive fatigue, spitting up like crazy vaginal discharge that is watery. I had enough Bd while on my fertile window as you can see at the bottom here so why am I still getting bfn 😔?
