Hi. I had protected intercourse for the first time in my life on april 1 and since then I am having lighter periods from last 2 months. The periods are lasting only for 2 days. Then they get stop amd then on 4th day I got little bit of blood once and then no period at all. I tested on preganews thrice. They all were negative. My thyroid and prolactin levels are fine. I went for the ultrasound and now I am diagnosed with pcod. But there shows a minimal fluid in pod as well. So is this minimal fluid normal? And this is not related to pregnancy? My period date was 11 may and I went for the ultrasound on 23 may. Please suggest?
