No Period - Help!!!

Hi, so on the 14th February last year I went on an extreme calorie restrictive diet. Ate just over 1000 calories per day for almost 4 weeks. Weight literally fell off but unfortunately my period stopped. I had numerous tests done and was diagnosed with Amenorrhea. My period didn't come for 8 months until I went 'all in' in October. I ate around 3000 calories a day and within 20 days it came back. As you can imagine I was ecstatic. I gained roughly a stone in this time (weight gain didn't bother me) and have had three periods since. (12th November, 16th December and 11th January). Since My last period I've gained about 2lbs (currently at a weight were I always menstruated at) However it hasn't come yet and I'm seriously worried I've messed up. Last week I went on a diet (ate roughly 1190 calories a day) and now I'm on day 32 and it's not here. Do you think I've knocked it off by cutting slightly? P.s. Zero chance of pregnancy 😉

I nearly cry every time i even think about it. Do you have any advice or guidance? Any feedback welcome.
