I've lost weight but no way to know how much

Okay before i begin let me just say this I'm not obsessed with whats on the scale, I know that scales are not 100% reliable when giving you total accuracy!

When I started my weight loss journey Feb 22nd the following Friday I weighed myself and in one week I went from 252 to 246! The next week I weighed myself in the morning again after i peed like I did the Friday before that and the scale told me I was 251! I'm going to be honest I felt my motivation level decease a bit but I remembered how inaccurate scales could be. Skipping to the ahead to the next week I weighed myself in the morning and it was 249, but this time I moved the scale from where it originally was to someplace new (my entire house it hard wood floors btw) and it went up! *sigh* it's bothering me because I know I am not gaining weight Its noticeable that I've lost! in my hips , sides, back, bum , arms , faces and also my muffin top is shrinking. I want to add how much I've lost to myfitnesspal profile other than the lbs I added when i first weighed myself which was 5lbs, so that as I go along with my fitness journey I can adjust my calorie intake but How can i do that if i don't know how much body fat I've actually lost! I've been looking things up to find a solution before I came to post this and came up with nothing to help my situation, so Any advice on what I can do regrading to alternatives to finding out how much body fat I've lost or even to get a some what realistic estimation so that i can add it to my weigh ins on my profile would be very helpful.
