Girls, hi! I went for an appointment with a gynecologist today, she has 49 years of experience. I told her about my miscarriage situation and she looked at me, said there's no pregnancy, I need to get blood tests for hidden infections and check the thyroid gland. Who was in such a situation? I'm completely confused, it could be that something is happening to me ?‍♀️
