Asking for advice or insight

Three days ago I started spotting light pink, which was seven days before my expected period. Hubby and I barely bd this month and I never got a positive opk so I am almost 100 percent sure we did not make a baby this month. On day 2 of spotting it turned red and got a little heavier, I never filled a tampon, but the tip (tmi) was slightly filled and it was red & Brown I believe. So now I'm on day 3 and I have had nothing but a very little amount of baby pink when I wiped one time. My periods usually come around the time Glow predicts and I usually either spot for a day or start full flow with massive intense cramps on the first day. What do you think? I really really don't think we could have conceived we bd maybe 4 times last month and like I said before idk when I ovulated but I'm sure we didn't bd around the time I THINK I would have ovulated... 😬😩
