How early is too early if you know your body?

Chelsie

We tried conceiving on the 23rd of Jan. According to my glow calendar my ovulation was the 25th. I have been having moderate to severe cramping since Jan the 28th. According to the articles I have read most women don’t have symptoms until the 9th day. Sometimes I do cramp during ovulation but not like this. Has anyone had this experience before?
