Did you have to REACH a certain weight number to get it back ? Or was the number different when it came back

I know this question gets asked a lot maybe or I’ve asked it before but it’s so hard finding much experiences or info on this specific bit.

Can I ask did you have to reach the same weight you were when you lost your period or it’s not related ? I’m confused because I’m under the weight I was when I lost it, but I’ve gained 9 kg from my lowest ever weight which was slight underweight , but I lost my period at 69 kg , when I started over exercising etc, and I kept losing weight, I dropped down to 51kg before entering recovery and now I’m 59 kg , but I just don’t know that if I keep staying in recovery and for example reach like 60-62 kg can my period return I’m 3.5 months into recovery and I’m just wondering if it’s been the full 6 months of all in for example, will my period return regardless or whatever number I am at that point ORRR will my period like never return unless I’m 69 kg ? That part confuses me.

I have a long history with obesity and losing and regaining weight multiple times so the numbers are all over the place but I tried to give the most relevant recovery numbers for my situation above
