Having a thyroid problem really messes up your hormones as well as your periods so it will be difficult for you to get pregnant if you are trying. As for being a virgin and missing it you are fine. Stress, anxiousness, fatigue, and being over active are all results of why you may have missed a period or are late. STILL CHECK WITH YOUR DOCTOR and definately let your mom know, she may know what to do.
