am i just not ovulating?

Brittany

these tests are from 3/20 - today.

they all look the same with no change.. this app says i should ovulate in 4 days but my premom app says i should have already ovulated. i’m cramping soo bad and have bloody discharge. my period ended on the 15th.. i’m soo confused.. first real time ttc. my last two pregnancies we weren’t actively trying.. can someone help me understand what it going on??
