Administarative processing- any significance of a change in status update date

[AH4]

I am currently on H4. Was on F1 for 5 years when I was doing my post grad in a STEM field. Attended interview on the 19th of december, 2016. Husband got visa, my passport was retained and I was handed a white slip asking further information that I furnished promptly. After all this waiting, last status update date changed to 30th Jan for the first time since the interview date, but still shows administrative processing. Is this a good sign or should I not read too much into it? Sharing any similar experiences from the community will be of great help. Thanks!
