Hi, Well in my 20's, I had a couple of long stretches with no period like you describe. I too was stressed at the time. It turned out that my hormones were out of whack. In my situation, I was producing too much estrogen. My thyroid was out of whack as well I had hypothyroidism. Often if someone is anxious or depressed (even minimally as it didn't really interfere with my life and I didn't seek medical treatmen for it, it was just a difficult time)--- the thyroid gets involved. Hormones and mood are very interrelated. Symptoms of hypothyroidism is slight weight gain, dry skin, and more.
I had an appointment with an endicrinologist but things resolved with me before the long wait for the appt. so I never ended up going. I've had no trouble with too much estrogen since then and have gone on to have completely regular periods and two children.
It was my ob/gyn that was able to discern that I produced too much estrogen and had hypothroidism.
So, I think having amenoria is reason enough for a more thorough evaluation and your physician should either do that or find another doctor, good luck
I agree you need a new Dr.
Also stress can cause your body to do strang things, like mess with your period. I used to go 6 months without mine and there wasnt a thing wrong with me, but everyone is different.
I would call around and find a good OB/GYN
Get a new doctor! If you have gone without a period for four months and you are not pregnant a gynecologist needs to examine you!
