Adjustment of Status - I-485

Hey there i've been a silent for quite awhile now and this forum seriously helped me to keep being patient during this whole process but lately i've been losing hope. I know I may have not waited as long as some of you have but lets be honest here.... the waiting game is killing me slowly.

Here's my timeline... (marriage to USC)

01/28/17 mailed my i485, i131, i765 to chicago lockbox
02/02/17 they received my package
02/13/17 received the receipts
02/18/17 received the letter for biometric
02/27/17 biometric done

Since then nothing!!! I'm getting more and more anxious because my brother in law is gonna get married this summer in my hometown (he met his fiancée online who happens to live in the same city as me what a coincidence!) and I'm afraid I wont be able to come with my husband's whole family. I havent been home for 6 years and it'd be nice to visit with my husband :( i pray for all of us here to be patient during the process and will hear good news soon!!

God bless yall!
