Adjustment of Status - I-485

Hi everyone, I am new to this forum.I have been reading everyones experience and keep comparing their timelines to mine and what I see doesnt make me happy...
I submitted my i-485, i-130 and i-765 on Feb 16, 2018. They received my AOS package on feb 20th. I got a rejection letter for my work permit that's why I had to resend it. I got my first biometric appointment ( for i-485 and i-130) on March 28th. I sent my i-765 for the second time on March 6th and they received it on March 14th. I mean this is the date that they received my case on the notification letter that's they send me. I got my second biometric appointment on April 11th for my work permit. And since then there is no updatea on any of my cases whatsoever. My I-485 still says that fingerprint fee was received since March 5th and my i-130 says that case was received. Also my i-765 still says that case was received. I have seen so many people who got their online updates about their interview to be scheduled but I'm not getting any updates. I haven't received any evidence request so far. Do you think there's a problem with my case? Is there anybody who never got any updates also haven't received their work permit yet? I keep checking my status 1000 times a day and I am really frustrated with the whole thing. Please share your timelines or experience with me. I hope all of us hear something soon.
