Hardly any periods

Br

Since August I have literally had 1 period and that was in November. I went to doctor and got an ultrasound/ blood work. Everything came back normal. Minus 1 cyst on my left ovary. Just routine blood work and an ultrasound. Both internal and external (I think thats the term lol) nonetheless...I used to have a period every month and now I’m going on 2 missed periods since the November one! Has anyone had this issue? I am not ttc at the moment but we don’t use protection as we are married. He does use pull out method but we truly aren’t avoiding pregnancy. It’s just stressful not knowing my body anymore lol I hate pcos
