Are my gums growing back? (Photo)

I had laser gum contouring two days ago 5/8/17 and the immediate results were pretty good. The following day, I noticed quite a bit of blood around my gum line. 3 days post, I'm noticing the gum line isn't as high as it originally was. Is it possible for my gums to grow back completely?is it just swelling/bruising that'll go away? Also, how long does it usually take to see final results? I'm supposed to go back for a follow up this upcoming Monday which is exactly 7 days after the procedure.
