Router-on-a-stick configuration in OSPF?

Hello there friends. First of all, I want to congratulate myself for passing my CCNA R&S and right now I am doing some practice on my own. Here is the situation. I have a network in router A which has a different vlans on it so I configure to run a router-on-a-stick and it runs fine. Later on, I decided to add another router which is router B and it also have different vlans in there (also Router-on-a-stick runs smoothly). Now I want router A hosts to communicate with router B hosts so I used OSPF on it but the problems seem to be on the subinterfaces I think? Because it did not advertised all of the networks inside Router A to Router B. I could see that there is adjacency changes but when I issue #sh ip route all I can see is directly connected and no signs of ospf at all. I am new to CISCO so I hope you guys could guide me on this.

Your two routers, for their local "stick" routing, don't require any routing protocol for them to route between the locally connected VLANs.  So, if you're enabled OSPF, I wonder, are your local VLAN networks make known to OSPF?

PS:

As Mfurnival has asked, posting the router configs would be a huge help.
