Help me ladies!

I'm 24 with a 4 year old daughter. 3 months in. I had my period the 10th -14th and started taking opks the 16-24th when I ovulated on the 20th. The bottom two are from this morning bright as can be. I've read this is a sign of pregnancy before prego test can picj up the levels of hcg. Here's a pic of the opks what do yall think?
