I’m 5 months and from October. So I wouldn’t get too excited. I’d just keep on waiting.I hear you, I also have waited 4 months after DM and I applied in October. We just have to continue waiting for now.
You may be lucky to get called for August, I have heard of some November applications going for oath here so it's possible.
However, if I were you I will postpone my travel unless it is absolutely necessary in which case I will notify CIC about my trip to ensure I am not scheduled for that time.
