Stressed!!

Hey everyone! I am a very very stressed person no matter how little I think about it constantly and stress about it until I know and it is an awful thing I do but recently about 6 months ago I had a pelvic ultrasound and my ob said I had a small follicle cyst on my right ovary and that they could not see my left well now I am gonna have another one to get checked up and to check the cyst see if it’s gone or not but I’m really worried that I will have pcos. And I am only 18 and I worry about everything but what I really want is to have kids when I’m older all night tonight I have been worrying about what if I have it and I always worry if I will be able to have kids because last year I got a nexaplon in and since then I haven’t really had any discharge and my periods have been wonky but all in all I’m just worried about what if they tell me I have pcos. Does that mean I will be able to have kids when I’m older or if I won’t and I have all these things going through my head.
