Pretty sure im out this month

Starly • Married, Mommy of a 4 year old, ttc baby #2

Been spotting for 4 days now, nothing to soak a pad. Temp dropped today , today was my estimated AF date. I don't understand though, I got high fertility from the 10th to the 15, positives on the 16 & 17th with 2nd MU. I can't help but think I didn't even ovulate.

Wishing the rest of you ladies better luck
