Can your period come and go?

mommy of 1

My lo is almost 8 months old, my period returned after 6 months pp, 7 months my period was 3 days early and this month I’m 5 days late. I have been having cramping like I was going to start my period but nothing. I took a test 2 days ago and it was negative, taking another test in the morning. But can your period come and go? Starting to freak out.
