Not losing

I had revision to rny 1/7 and I have only lost 5lbs since. I just came off my cycle and have pcos. My revision was due to reflux and a severe hernia but I had gained 1/4 of my original loss back. I guess I was expecting to see more loss even though that wasn’t the priority. I haven’t even started solids, still shakes and a little yogurt and plant based soup (which after over a month is getting to me)… my calories before surgery weren’t that high (I lost 16lbs in the 3 weeks before surgery)… I just seem stuck here…
