Oil leak after head gasket replacement

Help: So I replaced my head gasket myself about 3-4 months ago and when it was time to do an oil change, I noticed an oil leak and almost two quarts missing. I was hoping it was the timing cover because it was only to that side, but to my dread, it does look like it maybe the gasket, but it's hard to tell being so close to where it meets the timing cover. Any advice or tips on how to proceed / what potentially I did wrong? How much time do I have with a slow oil leak potentially from a HG because it might be a while until I can tackle this project again, will driving it and topping off be okay for a bit? Thanks.
