Slow weight loss

I am 23M, 6’ 0”, currently 213lbs. I have been consistently working out with a mix of weights and cardio at least 4-5x a week for about 1.5 months and have only seen minimal weight loss. I wake up and weigh myself at 213lbs, and when I started I was 216/217 when I woke up. I am absolutely positive that at least 6 out 7 days a week I eat under my maintenance calories, and I just cannot seem to lose weight. I am starting to get really discouraged.

If anyone could offer some advice or what they think the problem may be, I would really, really appreciate it.
