so confused! AUNT FLOW?

BreAnne • Due August 22nd. Elijah Michael 💙👶

hey girls! so I finished off the last of my birth control pack, taking the last pill, on Tuesday October 3rd. This was also the day my SO and I began TTC. Now, when I was on birth control, aunt flow came like clock work. She would've came Saturday the 28th. Instead, she was 6 days late and started on Friday November 3rd. I figured it was just messed up from me ending my birth control. But, my period was literally red and normal for only that first night on friday. The next day it was barely there and was dark brown. By Sunday it was completely gone. I have never experienced this before. Is this just my period trying to get back to normal after taking the pill for so long or could it be implantation bleeding? What are your thoughts?
