Hello loveisblessing, you should only take this info as a reference, you have a long road ahead and patience is a virtue. Both uscis and nvc are obscure and will not tell you exact times, it helps calling them to ease you anxiety, you should base your time frame from a combination of both visajourney and uscis but nether will tell you when you are going to be approved. In my case, with nothing wrong on my forms, it took 6+ months. But many other people passed right by. Keep calling until you can finally be allowed to put your case to a tier 2 supervisor. But hopefully you will get approved before you need to. It is said that after 5 months you can get this option but uscis will do everything they can to keep you guessing. my thoughts to you is to be patient and keep your mind out of this as best you can. You will get your notification soon. Best of luck.
