Sudden long cycles

Hi,

I’m in desperate help here.

I’m a female 28. For the past 1,5 year maybe, I feel my period is changing. I never really “miss” a period but the cycles are getting longer. I’ve averaged 30-31 days most of my life, but now I’m around 38 days. I also lost the feeling of sore boobs before my periods and I don’t bleed as heavy as before. Which might be good..? Not sure. Anyway, I also feel quite moody than before. When I bleed, I do bleed “normal” but the period is lasting like 3-4 days and then it stops. I always used to bleed for 6-7 days.

The thing that worries me the most is that my vagina feels overall drier than it used to be. I can still have intercourse but it’s not as moist as it used to be. Can it be low estrogen?

I went to the doctor and requested a AMH test just to check my eggs and he said I had 5.7 or something which is high.

What is happening? I’m really worried since I feel like my body is suddenly becoming unpredictable
