Chemical pregnancy?

Brittany • Twin mom! My identical twin boys just turned 3 this June (2020) and our daughter is 1 1/2! Full time therapist and mom of 3 kids all 3 and under.

I’ve been breastfeeding twins for the last year so I finally got my first postpartum period on May 1st. Next period was due May 30th according to what my cycles used to be like. I got positives on a couple tests and a couple negatives IN BETWEEN the positives. Today I got a big fat NO on a first response digital. Still no bleeding or cramping and I’m 7 Days late. Is there any hope??
