Confused

Hey everyone,

I use opks to figure out approximately when I will ovulate. I’ve been doing so since Sept ‘21. I usually ovulate around cd 12. In January, I ovulated around cd 16. Back to normal in February.

This month, it was looking like another late ovulation (for me), but I was out of town and unable to catch if I had an LH surge. I started having the flashy smile on clearblue digital on cd 12 and it went all the way through to cd 17 before I ran out of strips. So I didn’t catch when I had a surge this month. That being said, I don’t know when to expect my cycle.

AF is “due” in 3 days, if I ovulated on cd 14 (which I find unlikely since I was tracking).

Today I have had light brown/pinkish spotting. I have never had spotting before.

Is this likely my cycle starting early, or could it be implantation?

My husband and I BD’d although my fertile window, I just couldn’t confirm ovulation.

This is my seventh month TTC and just probably am grasping a straws.

Any advice or opinion you may have on my situation is appreciated!
