need help calculating why i’m not seeing weight loss

Hello, so I am currently 134 lbs (19f) and I am trying to get back to my normal weight of 127/125. I am 5’2 and I have been running 3 miles everyday for the past week (6.7 speed on the treadmill), took a rest day on Tuesday, and yesterday was busy from sun up to sun down so I didn’t have a chance to get in my miles. I’ve also added weight lifting and I’m seeing some toning.

But I weighted in on the 17th at like 134.6 (mind you this was a day after I finished my period) and then on the 21 i weighted in at 132.9, it’s now been a week and i’ll give you my calorie intake since then

22- 1289 (with workout 1114) 23- 1262 (with workout 974) 24- 1444 (with workout 1258) 25- 1484 (Rest Day) 26- 1331 (with workout 1104) 27- 1110 (no workout)

on the 25th I weighed in at 134.8 but I couldn’t have gained a pound when I’ve been in a deficit. My TDEE with light exercise is 1837, so I’m at least about 400 down a day without my workouts per week and even more with working out. I searched this reddit before and someone said the ovulation period can make you gain weight, but I’m not sure if I’m doing something insanely wrong? I have been drinking around 56-80 oz water per day (each day i have been drinking about 64 oz with the exception of yesterday)

today i weighed in at 133.7, so down from the 25th, but I’m just a bit confused. I used to have an ED so I don’t want to cut heavy calories but I thought I would at least see minor results by now (by minor I mean I thought I would at least maintain 132.9 or lower to 132.6)

Any advice would be helpful.
