3 days late?

G ✨ • Mama to 2 little girls. 2 years old and newborn • May babies

3 days late- 2 negative pregnancy tests. I am never late my period is typically 7-8 days long and a 28 day cycle. It starts on the exact day it should almost always. I am 6 months postpartum and did not breast feed, cycle came back at 7 weeks postpartum. I was in the mini pill for 3 months but it was causing issues and I stopped mid-pack this last pack. Did not experience any spotting as a result and now my period is late? Suggestions?
