Mid cycle cramps..

Shawnna • Currently Prego with baby #2. TTC for 11 months before bfp. I have one daughter she is 8yrs old
OK so. My AF is 6 days out. And for the past three days I have been having this weird cramp like pain.. But only on my left side. Tracking my ovulation is hard for me and hit or miss. Been TTC baby #2 for 5 months. I have a 7yr old already.. What is this weird pain? Normally I get cramps on my first day of AF.
