Houblonmontre fermentation

Ok, so I’m on my 5th brew, the houblonmonstre, i did a yeast starter and its been bubbling for 14 days. It seemed pretty aggresive right off the bat, and the foam has been going down ever so slowly, but theres still a couple inches and bubbles every 5 seconds or so. Room temp is around 67-70, is there anything i should be concerned about? All of my others bubbled for 2-5 days and then done so it has me wondering!? How long should i expect this to go on?

Nothing to worry about, mine was very aggressive at first, so much so that it came clean through the blow off hose into the sanitizer bucket. It then proceeded to ferment for quite a while, although I forgot how long. I gave it 3 weeks and moved it to my secondary where it still sits, but I’m going to be bottling it first chance I get.
