My cycles have never been normal. I started my period when I was 12. I am now 28. I've been off birth control for about a year. I have exams every year so my dr is on par with my problem. Last year I had two rounds of lab testing due to the fact that I have symptoms that mimic PCOS. My labs all came back normal. Last year I only had three periods, this month my period was 5 days late and no positive pregnancy test. My dr wants to schedule an ultrasound and more labs. I am generally healthy, not over weight, I dont eat a lot of sugar (due to diabetes running in my family), and I dont over exercise.. I just want to know why all of a sudden they want an ultrasound now? I feel like I'm so alone with all this and on top of everything my husband and I want to try to get pregnant in the next couple of months. I'm so scared.
